Instead of using the project's $(libdir), $(datarootdir), and so forth,
I use pkgconfig to interogate guile-2.2.pc or guile-2.0.pc, and install
source (.scm) files in its revealed 'sitedir' and compiled (.go) files
in its revealed 'siteccachedir', with the base project module name
added to the path in each case.  That way, even if the project
(including any of its shared library files) are installed in, say,
the /usr/local prefix, the scheme files are installed in the correct
prefix for guile.

That is presumably why 'sitedir' and 'siteccachedir' are exposed by
pkgconfig.
