[mod_python] mod_python 3.0.1: problem with libtool and apache

Hi All.

Thanks a lot for the previous answers.
I replaced the old libtool apache come with, but when I make apache I obtain
an ugly message...

libtool: link: cannot find the library `'
make[1]: *** [httpd] Error 1
make[1]: Leaving directory `/usr/src/httpd-2.0.43'
make: *** [all-recursive] Error 1

What does it mean?

Thanks in advance.

Gius.
