The clang compiler doesn't honor LIBRARY_PATH during linkage. For example, when
building guile 1.8.8 using clang against libgmp in /sw/lib...

setenv LIBRARY_PATH /sw/lib

allows both gcc and ifort to find libgmp in /sw/lib without explicitly passing
-L/sw/lib on the compiler options...

[MacPro:guile18-1.8.8-3/guile-1.8.8/build] root# gcc -o conftest -g -O2
-Dmacosx conftest.c -lgmp -lm -lltdl

however this same configure test fails to link under clang...

[MacPro:guile18-1.8.8-3/guile-1.8.8/build] root# clang -o conftest -g -O2
-Dmacosx conftest.c -lgmp -lm -lltdl
ld: library not found for -lgmp
clang: error: linker command failed with exit code 1 (use -v to see invocation)
