I found that on http://fedoraproject.org/wiki/Features/Guile2
"guile-1.8.8 should be properly obsoleted by compat-guile18.
guile-1.8.8 should be properly upgraded to guile-2.0.7.
If both compat-guile18 and guile-2.0.7 are installed, there should be
no conflicts."

which seems to confirm what you said: both libraries can coexist.
Maybe it is just configure that should be changed to select the right
guile.

I read also that:
"The packages will have to be patched to Require and BuildRequire the
compat-guile18(-devel) package. Furthermore, they will have to be
patched (if necessary) to use the renamed autotools macros. The
patches to spec files and autotools macros are easy to implement.
Packages that are already built will not have to be rebuilt (there are
no soname bumps in the compat package) and should function without any
problems. Only new releases will have to be patched."

This confirms that lilypond cannot be built without modification. I
just have to find these "easy to implement" patches... If someone has
ideas!
