Sorry for the delay in this. I believe I am nearly done with my tcl84  
and tk84 ports for use with blt. But I'm not sure how to handle the  
post-destroot in order to have both versions be able to be installed  
at the same time.

Here's the current one for tcl 8.5 (tcl):
post-destroot {
     ln -s ${prefix}/bin/tclsh8.5 ${destroot}${prefix}/bin/tclsh
     ln -s ${prefix}/lib/libtcl8.5.dylib ${destroot}${prefix}/lib/ 
libtcl.dylib
}

and for tk 8.5 (tk):
post-destroot {
     ln -s ${prefix}/bin/wish8.5 ${destroot}${prefix}/bin/wish
     ln -s ${prefix}/lib/libtk8.5.dylib ${destroot}${prefix}/lib/ 
libtk.dylib
}

For example with tcl 8.4 (tcl84), I don't think I can simply change  
the version because it will overwrite the symbolic link:
post-destroot {
     ln -s ${prefix}/bin/tclsh8.4 ${destroot}/${prefix}/bin/tclsh
     ln -s ${prefix}/lib/libtcl8.4.dylib ${destroot}/${prefix}/lib/ 
libtcl.dylib
}

Any suggestions on how to handle this issue?


Cheers!
