There are problems when configuring with the default CFLAGS (-g -O2  
above).  The debug flag causes trouble with configure in some cases.   
Set CFLAGS and CXXFLAGS explicitly before running configure, like:

export CFLAGS=-Os
export CXXFLAGS=-Os

(-Os is the standard OSX optimization)

If you really want debug symbols, then you must edit platform.make  
after configuring to add -g to CFLAGS and CXXFLAGS.
