Guix doesn't/shouldn't make use of LD_LIBRARY_PATH, except in rare cases
to wrap binaries.  It's better to patch the dlopen calls to use the
absolute shared library file name.

Perhaps you are missing the package configuring LIBRARY_PATH and other
useful environment variables for finding libraries?  That'd be
gcc-toolchain, if I recall correctly.
