Installing mod_ntlm into Apache in AIX 6.1   

Hello, i'm trying to compile mod_ntlm into Apache2.2.13 on AIX 6.1 but i'm confused as the apxs utility doesn't create .so file but instead i get .a and .la files, these are in the Apache modules directory as well. Apache is compiled with following options:

./configure --enable-so --enable-cgi --with-included-apr

When i try to create the module it always fails on not being able to find the .so module:

Stop.

Anyone has similar problem? Or anyone can explain to me the difference between creating .so and .a/.la files?

Just a small update on this topic, on AIX 5.3 it works as it should, tried the same compliation:

checking whether the gcc linker (/usr/bin/ld) supports shared libraries... yes
checking dynamic linker characteristics... aix5.3.0.0 ld.so
checking how to hardcode library paths into programs... immediate
checking whether stripping libraries is possible... no
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... yes
checking whether to build static libraries... yes
