--with-mnogosearch
http://www.mnogosearch.org/history.html
Probably fixed in "24 Sep 2001: 3.2.0" but this is development 
version of mnogosearch.
What version of mnogosearch do You use?
Compilation pass without --with-mnogosearch?

nope :(

:((((

I'm a bit tired of this problem.
It's a completely different machine, but the error is
the same.
So, it would be great if a PHP developer could help to us...

Same issues but with RedHat 6.2.

Like the original poster, I also copied libtool from my 4.0.6 installation and it works fine.

This could happen for example if you compiled mnogosearcg statically with mysql and trying to compile it with php, which is also required mysql. So you are linking mysql twice. 

To fix this - just compile mnogosearch and php with dynamic libs not static.

This bug has been fixed in CVS.
