I was indeed trying to do this.

This worked fine.

This did not, I am getting this error:

configure: checking for guile 2.2
configure: found guile 2.2
checking for guile-2.2... /usr/bin/guile-2.2
checking for Guile version >= 2.2... 2.2.3
checking for guild-2.2... no
checking for guile-config-2.2... no
checking for guile-tools-2.2... no
configure: error: 'guild' binary not found; please check your
guile-2.x installation.

Then ran
$guix package -i guile
Same error running configure.
$guix package -s guild
$guix package -i guildhall
And my output of guix -I, however, is:
hello    2.10    out    /gnu/store/bihfrh609gkxb9dp7n96wlpigiv3krfy-hello-2.10

/gnu/store/kd2mvhr18yphrkiqgavw0w0r0n5bfchn-guildhall-0-1.2fe2cc539

Something weird  is that in configure output I see there is a /usr/bin
mentioned, so I went to that dir, ran
$ ll | grep guile
lrwxrwxrwx  1 root root          23 oct 10 22:55 guile ->
/etc/alternatives/guile*
lrwxrwxrwx  1 root root          43 jul 17 10:42 guile-2.2 ->
../lib/x86_64-linux-gnu/guile-2.2/bin/guile*

And can't figure out why I have that links.
