Marcela, again, again and again: Watch out _before_ you cause unowned/orphaned 
directories, please! The directory /usr/share/tk8.4 is no longer owned by any 
package but should be owned by tk (like before):

W: tk dangerous-command-in-%pre rm
   It appears that the %pre script attempts to remove a link named
   /usr/{lib,lib64}/tk8.4.  Why does it do this?  Is this an attempt
   to clean up a link that was erroneously made in a previous version
   of Tk?


GOOD
====
* Package named appropriately
* Sources matches upstream
* Spec file legible and in Am. English
* BSD license ok, license file included
* Build dependencies ok
* No locales
* No need for a .desktop file
* ldconfig called correctly for libraries in %{_libdir}
* Not relocatable
* No duplicate %files
* No need for -doc subpackage
* headers and unversioned .so files in -devel subpackage

MUSTFIX
=======
* The 'URL:' tag is the -devel package description is redundant; the url
  defaults to the one specified for the main package.

* As mentioned in comment #1, the /usr/share/tk8.4 directory is unowned.
  The patch in comment #1 will fix it, and simplify the %files section.

* Mixed use of $RPM_BUILD_ROOT and %{buildroot}.  Choose either one and use
  it consistently.

* Move the %{_mandir}/mann/* man pages out of the -devel subpackage and
  into the main package; these are man pages for the script-level API, not
  the C-level API.  The %{_mandir}/man3/* man pages can remain in the -devel
  subpackage.

* The TOPDIR=$PWD at the top of %build is unnecessary.  Remove it.

NOTES
=====
* package does not currently build because Tcl is not providing
  the private header files in /usr/include/tcl-private.  This is a
  bug in the tcl package, not tk.

* The summary shouldn't contain the package name.  You should drop the
  'Tk' from the summary and capitalize the 'g':
  Graphical toolkit for the Tcl scripting language

> W: tk dangerous-command-in-%pre rm

It should remove old directory before installation, if exists.

All MUSTFIX items fixed.  Directory ownership looks ok nw.  /Resetting the
