Altered configuration variables:
shared = False (default True): build shared libraries, not static
strip = False (default True): build with stripping of binaries enabled
prefix = /sw (default /usr/local): installation directory prefix
scons: done reading SConscript files.
scons: Building targets ...
Install file: "gps/clienthelpers.so" as "/tmp/crap/Library/Python/2.7/site-packages/gps/clienthelpers.so"
strip /tmp/crap/Library/Python/2.7/site-packages/gps/clienthelpers.so
