That's the part that wasn't in your original mail.

And from your config.log pastebin:

configure:4272: checking for mysql_get_parameters in -lmysqlclient
configure:4297: g++ -o conftest -g -O2   conftest.cpp -lmysqlclient   >&5
/usr/bin/ld: cannot find -lmysqlclient
collect2: ld returned 1 exit status

At this point, all I can guess is that you haven't installed the 
libraries correctly for your system.  Can you do a simple command line 
test (rather than through autoconf) to rule out whether 'gcc ... 
-lmysqlclient' works in isolation for you?  Or maybe you are trying to 
access a symbol that is exported in newer versions of the library, but 
not in the version that you have installed?
