Libtool and C API: ld: common symbols not allowed

[Till Quack]

We are trying to build a library with GNU libtool (For Perl Inline::CPP)
on OS X Panther with the C API from mysql (And some other libraries like
Magick, which don't cause problems).

When using the libtool we get the following error:

libtool -dynamic KnnSearch.o ../common/extractors/htd/HtdExtractor.o
../common/extractors/htd/FFT.o ../common/extractors/ehd/EhdExtractor.o

-o libKnnSearch.dylib
ld: for architecture ppc

-multi_module option
/usr/local/mysql/lib/libmysqlclient.a(my_error.o) definition of common
_errbuff (size 512)
libtool: internal link edit command failed 

A similar problem has been discussed in 
http://mail.gnu.org/archive/html/libtool/2003-07/msg00104.html
However, we were not able to deduct any clues for our problem from this.

Any ideas on how to solve this issue are highly appreciated.
