The profiling support might not be thread safe.  While it may seem 
counter-productive to program tuning, it is usually recommended to use 
limited optimization, or no optimization at all.

As long as libtool is passing the -pg from CFLAGS to the compiler, and 
the -pg from LFLAGS to the linker, and the correct startup module is 
being used (indicated by a gmon.out file being written) then I think 
that libtool is no longer the issue.
