Missing libpython2.4.so during build of python 2.4.2 on AIX 5.1

[HajoEhlers]

Hi folks,
maybe somebody can help.
I am trying to build python 2.4.2 on AIX 5.1 with gcc 3.3.2

The build option for python are:
$ ./configure \
--enable-unicode \
--enable-shared \
--with-gcc \
--mandir=/usr/local/man \
--infodir=/usr/local/info

After make i see a libpython2.4.a in /usr/local/lib/python2.4/config
but not an libpython2.4.so .
Even the libpython2.4.a will not be installed into /usr/local/lib

From looking at the Makefile i was not not able to determine the option

which might be missing to get a shared library of python.

Any hints ?
