[MACTCL] Can't find install directory properly on OS X.

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

My apologies if this is an answered question (couldn't find it in
archives), but I'm having difficulty getting 8.3.2 to find itself properly
after installation.  I have similar problems for everything else
thereafter (tk, itcl, itk, iwidgets).  

The quick fix is to set the corresponding XXXX_LIBRARY environment
variable to the packages find what they need, and all is good.  But that
doesn't fix the problem, it quells the symptom.  How does
/System/Library/Tcl/8.3 get into that search path and how can I go about
to get that to be based off --prefix's value. 

There is a little oddity of the Makefile getting modified (necessarily on
other platforms) prior to building.  The details are included below.  Any
help is appreciated. 

As a side note, I have to use 8.3.2 for this release, unfortunately.
Then I'll be upgrading it to newer tcl/tk sources.  A short-term fix to
get this version working would be nice, though.



Here is the error message:

bash2.04 sean@dhcp-32-233 ~/brlcad6/.libtcl8.3.pmac % tclsh
application-specific initialization failed: Can't find a usable init.tcl
in the following directories: 
    /System/Library/Tcl/8.3 /usr/brlcad/lib/tcl8.3 /usr/lib/tcl8.3
/usr/lib/tcl8.3/library /usr/library /usr/tcl8.3/library /tcl8.3/library
/System/Library/Tcl/8.3


This probably means that Tcl wasn't installed properly.



Here is the initial build:

The fix_makefile.sh file looks like this:
bash2.04 sean@dhcp-32-233 ~/brlcad6/.libtcl8.3.pmac % less ../libtcl8.3/fix_makefile.sh 
#!/bin/sh

sed -e s@lib/tcl\$\(VERSION\)@tcl\$\(VERSION\)@ Makefile |\
         sed -e s@\(prefix\)/include@\(prefix\)/include/brlcad@ |\
         sed -e "s@\${\C\C}  \${TCLSH_OBJS}@\${\C\C} $LDFLAGS \${TCLSH_OBJS}@" |\
         sed -e "s@\${\C\C}  \${TCLTEST_OBJS}@\${\C\C} $LDFLAGS \${TCLTEST_OBJS}@"




Resulting in the following diff in the Makefile:

bash2.04 sean@dhcp-32-233 ~/brlcad6/.libtcl8.3.pmac % diff Makefile.pmac
