Mega patch to improve how build dependencies are handled and

how packages are found.

First: I removed all these *-deps.db files and only a single file
is used now "build-depends.db"; it's smaller and will be easier
to handle in the future... when "run-depends.db" is added :-)

Second: there's no need to specify version of package anymore;
before you had to do:

	$ pkgfs.sh install git-1.6.0.2

now you only do:

	$ pkgfs.sh install git

This will read the variables located at PKGFS_TEMPLATESDIR/git.tmpl
and will the install the version that is there.

+long_desc="
+ Pango is a library for layout and rendering of text, with an emphasis
+ on internationalization. Pango can be used anywhere that text layout
+ is needed; however, most of the work on Pango-1.0 was done using the
+ GTK+ widget toolkit as a test platform. Pango forms the core of text
+ and font handling for GTK+-2.0.
+
+ Pango is designed to be modular; the core Pango layout can be used
+ with four different font backends:
+
+  - Core X windowing system fonts
+  - Client-side fonts on X using the Xft library
+  - Direct rendering of scalable fonts using the FreeType library
+  - Native fonts on Microsoft backends
+
+ Dynamically loaded modules then handle text layout for particular
+ combinations of script and font backend.
+
+ As well as the low level layout rendering routines, Pango includes
+ PangoLayout, a high level driver for laying out entire blocks of text,
+ and routines to assist in editing internationalized text."
