Shouldn’t ‘GERBIL_LOADPATH’ be in ‘native-search-paths’ of Gerbil, just
like ‘GUILE_LOAD_PATH’ for Guile?
In that case, you wouldn’t need this procedure. Perhaps, you’d need to
adjust the convention, though, so that libraries are installed to
lib/gerbil/ instead of lib/gerbil-* (not strictly necessary because the
search path mechanism accepts regexps, as used for XML_CATALOG_FILES,
but somewhat “nicer” IMO).
Thoughts?
We’d also need an item in doc/guix.texi under “Build Systems”.
Please let us know if you cannot work on it in the foreseeable future.
I might be able to make these changes if they make sense to you.
Thanks,
Ludo’.
