Added /opt/local/lib as well as /sw/lib

Fink stores libraries in /sw/lib, but Macports stores them in /opt/local/lib. We add both directories to make sure we find something. Note this might fail if a user has both Macports and Fink installed.
Included "fcmp.h" in "utils.hh"

Cannot call _sao_fcmp before declaring it, see
http://clang.llvm.org/compatibility.html#dep_lookup
Merge branch 'bugfix__sao_fcmp'
