Common practice is to arrange so that bindings refer to C libraries by absolute file name. For example: --8<---------------cut here---------------start------------->8--- $ grep /libgcrypt $(find $(guix build guile-gcrypt) -name \*config.scm) "/gnu/store/qc3k3kd458pgrqsc7ih641160q81npwq-libgcrypt-1.8.5/lib/libgcrypt") $ grep /libz $(find $(guix build guile-zlib) -name \*config.scm) "/gnu/store/rykm237xkmq7rl1p0nwass01p090p88x-zlib-1.2.11/lib/libz") --8<---------------cut here---------------end--------------->8--- HTH!
