It looks as though Guile-Reader hadn’t been rebuilt against Guile 2.2.

When switching Guile major versions, you need to make sure to run (in
Guile-Reader’s build directory):

  make clean && rm -f config.cache

and then run ./configure, make, make install.

Is this what you did?

Could it be that GNU Make was built with support for extensions with
Guile 2.0?  If that is the case, you may need to rebuild it as well.

That being said, I’d recommend keeping both versions of Guile around,
which is easily done.  For instance, configure Guile master with:

  ./configure --program-suffix=-2.2

That’ll give you commands like ‘guile-2.2’, alongside the ‘guile’
command for 2.0; libraries and header files will also coexist (info
"(guile) Parallel Installations").

Thanks, good to hear.  :-)  Out of curiosity, do you have pointers to
these projects?
