Loading shared libraries that are not TCL packages

I've created a Starpack that loads the mysqltcl package. This works
fine on one system that has libmysqlclient.so.15 (part of mysql
client), but the systems I want deploy to use libmysqlclient.so.14 and
my Starpack fails to run.

I doubt that my organization will update mysql accross all the systems
just to run my app. I know I can load shared libraries that are TCL
packages with a starpack. Is it possible to include libmysqlclient.so.
15 (not a TCL package), with my Starpack? If so, how do I do it?
