Sounds like Tcl 9 / Tcl 8 builds mixed up. My guess is the Tcl 9 build 
is picking up either Tcl 8 headers or stubs from somewhere or those 
packages have not been updated for Tcl 9. Extensions that use the 
standard TEA system for builds (and have been updated for Tcl 9) should 
have a tcl9 prefix in the shared library name. Your output does not 
reflect that which is suspicious unless those extensions do not use TEA.

Where did you get the tclvfs from?

Can you post your configure line?
