Do you think about using libltdl, to try to load db client libraries first?
I knew this hack but:
-what about mysql (and other engines) client versions
-what about library search paths (portability issues?)

Could somebody give me some hints - is checking for libltdl commonly used in 
KDE and where?
I only looked at http://lxr.kde.org/ident?i=lt_dlopen , especially here 
http://lxr.kde.org/source/KDE/kdelibs/kio/kio/kimageio.cpp#114
