   The gnome libraries change API from time to time.  To avoid 
incompatibilities, the gnome people change the directory structure at 
the same time as well (therefore, these three packages won't conflict). 
  For pkgsrc this means that when this happens, we cannot simply 
"update" the packages, as the API would be incompatible and dependent 
packages would no longer compile.  This is what happened, for example 
with evolution-1.4.

   That's the gal-1 API

> gal2 is: DISTNAME=   gal-2.2.1

   This is the gal-2.2 API (which is incompatible to gal-2.0).  When 
gal-2.2. was first imported, this should not have been just an update 
to the old gal2 package (instead, a gal22 package should have been 
created to ensure backward compatibility).

> gal20 is DISTNAME=  gal-1.99.11

   This is the original gal-2.0 API (well, almost -- the corresponding 
libraries never made it past 1.99.11, but that's a different story).

> Why gal20 and gal2?

   Because gnome-2.8.x depends on the gal-2.2 (gal2) API, while other 
packages such as gtkhtml-3.0 and evolution-1.4 depend on gal-2.0 
(gal20).

   Not all the libraries of the gnome project have their own homepage.  
If you know of a more specific one for gal, please let me know.

   I have added a comment about the different API versions these 
libraries implement.

   In a new project, you would probably use the latest version, while 
older applications may need an older version.
