I've finally managed to enable iTcl with my fedora builds, and am 
getting the following error in the tests:

   8/ 13 Testing examples_tcl
Test command: /bin/bash -c 
EXAMPLES_DIR=/builddir/build/BUILD/plplot-5.7.3/fedora/examples\ 
SRC_EXAMPLES_DIR=/builddir/build/BUILD/plplot-5.7.3/examples\ 
PLPLOT_LIB=/builddir/build/BUILD/plplot-5.7.3/data/\ ./plplot-test.sh\ 
--device=psc\ --front-end=tcl
Testing front-end tcl
application-specific initialization failed: Can't find a usable itcl.tcl 
in the following directories:
     /usr/share/itcl3.3 
/builddir/build/BUILD/plplot-5.7.3/fedora/examples/../utils/../lib/itcl3.3 
/builddir/build/BUILD/plplot-5.7.3/fedora/examples/../utils/../lib64/itcl3.3 
/builddir/build/BUILD/plplot-5.7.3/fedora/examples/../utils/../library 
/builddir/build/BUILD/plplot-5.7.3/fedora/examples/../utils/../../library 
/builddir/build/BUILD/plplot-5.7.3/fedora/examples/../utils/../../itcl/library 
/builddir/build/BUILD/plplot-5.7.3/fedora/examples/../utils/../../../itcl/library
This probably means that Itcl/Tcl weren't installed properly.
If you know where the Itcl library directory was installed,
you can set the environment variable ITCL_LIBRARY to point
to the library directory.

I can fix with:

export ITCL_LIBRARY=/usr/lib/itcl3.3

How is this handled on different platforms?  Is ITCL_LIBRARY set 
automatically by the itcl package (which seems reasonable)?

Also, what is added by enabling itcl?

Thanks!
