It sounds like you are trying to use libtcl.so (or equivalient) in your 
setup.  It is possible to make use of extensions if you initialize 
everything correctly.  It is also possible to build special-purpose DLLs 
that can actually include other extensions added, called stardlls.  See 
http://wiki.tcl.tk/15969 for more.  This enhanced setup provides a lot 
of flexibility for embedders.
