... Oh! <light dawns>

I believe you read the comment wrong.  It's _not_ saying "require gmime 
3", it's saying don't enable gmime 3.0 by default even if installed, 
require enabling it to actually get it (because as I said it's still 
broken, but people might want to specifically enable it for testing 

IOW, you do *NOT* want to enable gmime3 if you want a working pan, you 
want it disabled!!

Which it is according to the below output, so you're good to go. =:^)

However, even if you actually want it disabled and it already is, so you 
should be good to go, the question remains a valid one, because it's 
often useful knowing how to hard-enable or hard-disable things and not 
just depend on automatic detection and defaults.  Certainly, gentoo users 
at least don't want "automagic" detection and strongly prefer hard-
enabling or hard-disabling (generally controlled on gentoo via USE 
flags), because otherwise the package manager doesn't track the 
dependency and can uninstall a depended library and break the package.  
So gentooers at least have a strong interest in being able to hard-enable 
or hard-disable options, and indeed, a good part of gentoo's maintainer 
patching is often adding or unbreaking options to hard-enable or hard-
disable various deps, where the upstream option is either missing or 

And other distro users doing their own builds will likely have similar 
wants/needs, tho they may not be as strong if they're doing builds 
manually anyway.

So the question remains worth finding an answer to.

Note that I consider myself /far/ from an expert in autotools or pre-
build configuration in general.  Never-the-less, between reading the 
configure help output, checking what the existing gentoo ebuilds do for 
existing options, and reading git log and git show and/or patches 
directly when I need to trace a known change, I can often-to-usually get 
the config I want/need after a bit of experimentation...

OK, seeing the output above, and noting for example --with-gnutls 
corresponds to With Gnutls: yes, while --enable-libnotify corresponds to 
With libnotify: yes, and being familiar with both patterns, at first 
guess I'd say try variants of --with-gmime-3.0=yes and --enable-gmime-30 
(or --without-gmime3 or --with-gmime-3.0=no and --disable-gmime3 to hard 
disable it) and see if one of them works.

But since we know the commit to check we can do better than first-guess 
by simply seeing which variant it uses, and what its defaults are.  And 
we see this in the patch/commit (lines wrapped and separated with 
vertical space):


+  AS_HELP_STRING([--with-gmime30],[enable GMime 3.0 support 
(experimental, normally: no)]), [want_gmime30=$withval], 

+if test "x$want_gmime30" = "xyes" ; then

See that --with-gmime30 ?

So I'd try --with-gmime30 or --with-gmime30=yes to hard-enable, and
--without-gmime30 or --with-gmime30=no to hard-disable.  Now we know it's 
the --with variant, and it's gmime30, not gmime3 or gmime-3.0 or the 
like.  But as I said I'm not an expert, and I don't remember nor do I see 
it easily visible in the patch so I'd have to look it up or (easier) 
actually try it to see whether it's the --with-gmime30=yes/no variant, or 
the --with/without-gmime30 variant.
