Indeed I can _install_ only one guile version at the same time system wide.
But I _compiled_ the mentioned three guile-versions, which takes some
time. But once compiled 'make install' is fairly fast.

So my workflow is:
(1)
- Compile guile-1.8 from the tarball*
- install it via 'make install'
- build LilyPond as usual with from a git repository, I call it "lilypond-git"

(2)
- Compile guile-2.0.14 from the tarball
- install it via 'make install' (this throws out previous installed guile)**
- build LilyPond as usual with from a git repository, I call it
"lilypond-git-guile-2.0.14"

(3)
- Compile guile-2.2 from the guile-repository
- install it via 'make install' (this throws out previous installed guile)**
- build LilyPond as usual with from a git repository, I call it
"lilypond-git-guile-2.2"


This gets me LilyPond-versions with three different guile-versions.

[*] guile-1.8. from the tarball needs to be done with the configure-option:
./configure --disable-error-on-warning

[**] at least I never experienced any drawback doing so


There may be a way to point LilyPond to a certain guile-version
without the need to install this guile system-wide, but I never found
it.
