[MACTCL] Getting 8.3 to work on OS X.

[Christopher S. M. <mor...@AR...>]

I need a push in the right direction.  I've been spending some time
getting our "house" integration of 8.3.2 (tcl/tk 8.3.2, itcl, iwidgets,
and other mods) to install hitchless on Mac OS X.

I've basically gotten everything to work with one minor exception.  I have
to manually set the environment variables (at least TCL_LIBRARY and
ITCL_LIBRARY) for the tools to work.  They either fail or warn saying that
init.tcl or itcl.tcl (respectively) can't be found, listing the path
searched.  Can someone tell me what file(s) I should be looking at so that
this does not need to happen.  I know that my modifying the source so that
a particular instal path is also searched is not the right solution.  But
I can't seem to figure out how to modify that path properly.

Of particular interest, I notice that /System/Library/Tcl/8.3 is always
listed in the search path (which doesn't exist on my box for other
reasons).  Where is that path getting pulled from?  And, more importantly,
how can I get it to search my install path?

Cheers!
