I cheated, sorry: first patch prepared the configure's infrastructure
for the --with-tcltk/--without-tcltk including --with-tcltk=PATH.

And the second one introduced the TCLTK_PATH usage for substituting
the 'wish' in the Tcl/Tk tools.

Sorry for the confusion.

Yes, you're perfectly right.

Oops: didn't noticed that it is the tarball construction.

Thanks! And for the sanity: I do not think that the single quote
in the path it sane too. But as I was teached, "if we should
quote something, we must quote it". ;))

Thank you. Examined the 'origin/pu' and saw that you're already
incorporated the git.spec.in patch. I've found a glitch in it:
the right PYTHON_PATH should be passed. The patch follows.

By the way, when I was creating the git.spec from the git.spec.in,
I had the 'Version' field equal to the '1.5.1-rc1.GIT' and RPM
does not like the '-' characters inside the versions. Did
'tr - _' for specfile version and tarball name. The patch
follows.
