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 ?
Hajo
