[New-bugs-announce] [issue7541] python-config --ldflags doesn't pick up libpython2.5.a

New submission from Robin <robince at gmail.com>:

Using my python.org install:
robin-mbp:~ robince$ which python-config
robin-mbp:~ robince$ python-config --ldflags
-ldl -lpython2.5

But if I build a C file with python embedded, the above linker flags
result it in it embedding the system python. Obviously the -lpython2.5
is picking up the system one in preference to the one on the -L path.

>From Ronald Oussoren on pythonmac-sig:

The easiest workaround is to open a terminal window and execute the 
following commands:

  ln -s libpython2.5.a libpython2.5.dylib

This will ensure that the OSX linker knows that libpython is a shared 
library and links to this library. By default the OSX linker searches 
for a .dylib on the entire linker path and only then looks for .a files.
