> Well, for 0.10.13-1:

First, thanks for the excellent and detailed comments.
Since I'm working with upstream about some other small
issues, I'm merging the fixes and hope to upload an updated
package within a day or two.

A short checklist:
> * Explicit library dependency
> -----------------------------------------------------------
> On main package:
> Requires:       fftw, hspell

fftw - removed (yes it should be delegated to RPM)
hspell - move to hocr-gtk subpackage. This package
         uses gtktextbuffer (python bindings) which uses
         gtkspell which test at *runtime* for backend spellcheckers.
         Added a comment about that in the .spec file

> On -gtk subpackage:
> Requires:       gtk2

fixed.

> ** Requires
> *  Requires for -devel subpackage
>    * Every package which ships pkgconfig .pc files must have
>      "Requires: pkgconfig"

Fixed. I didn't check .pc files at all. Looks like I should write
a small script to test these things (supplement rpmlint...)

Fixed.

Their inclusion in the .pc file is correct since they are used
by the applications, either explicitly (tiffio.h and fftw3.h) or
implicitly (hspell via gtkspell). However, I'll have to digg deeper
to make sure *which* subpackage requires *what* (TODO)

> * Requires for -gtk subpackage

Fixed.

Hmmm... first time I see this consideration. It seems logical
but are these any guideline about it?

If it's a general problem maybe I can use your method as a solution
for this package, but it seems better to fix the AC_PROG_INSTALL
macro upstream (if they accept the same logic).

> * Desktop files
>   - Category "X-Fedora" is deprecated and should be removed.

Done. I must have got its addition from some obsolete guide
somewhere but I cannot find any reference to it now, nevermind.

> * %doc %_mandir
>   - Files under %_mandir are automatically marked under %doc

Removed the %doc.

Fixed. Will recheck other ownerships as well.

TODO. I need to check it again.

Fixed (changed all assignments to use @...@ so we won't have wrong
assumptions in general and respect ./configure selections even in
non-rpm builds -- e.g: ./configure --prefix=/opt/kuku --includedir=/foobar
Sent upstream.

Updated packages+specs - ASAP (a day or two).
