I checked. I installed lang/gcc8 and compared the system compiler's
search path with pkgsrc's.

$ LIBRARY_PATH=/foo/lib /usr/bin/gcc --print-search-dirs | grep ^libraries:|cut -f 2 -d = | tr : '\n'

/usr/lib/

The gcc8 from pkgsrc also puts /foo/lib/x86_64-redhat-linux/8.3.0/ and
/foo/lib/../lib64/ first, then all other 64-like directories, then the
actual /foo/lib I wanted.

Is this known/desired?


Alrighty then,
