There are 3 different ways to compile Tk under OS/2: for XFree86, for Open32
(this is IBM's porting level above Win32), and for PM.

To compile for Open32 and PM you need additional files, available in
$CPAN/ports/os2/tk/.  To be safe, download all of them, and unzip the files
with patches to be ready to apply.  If you work with a release of Tk later
than 402.001, some of the patches may be already applied, so use your
best judgement.

!!! You do not need to apply patches to .../os2/* files, they are
already applied !!!  Just ignore the patches not mentioned below.  (You
may want to apply one of them in reverse (-R to gnupatch) to get a source for
tcl/Tk.  Another one need to stay, it corrects bugs.)

A lot of problems are unresolved.  Please be patient.  All the Tk-ish
problem in tcl/tk port PLUS unability to do fileevents are

Building for PM
~~~~~~~~~~~~~~~
a) Unzip both
	perltk_os2_pm.zip
	perltk_os2_common.zip
   inside the main Tk directory.
b) Apply the patches in
	diff_pTk_for_os2_402
	diff_mTk_for_os2_402
   with
	gnupatch -p1 < patch-file-name |& tee 00patch
   or
	gnupatch -p1 < patch-file-name
c) Do
	perl Makefile.PM pm
	make
	addres
	perl__ -Mblib basic_demo
	perl__ -Mblib demos/widget
	make install
d) Do not forget you need to use perl__ to run PM programs instead of
   just perl!
