libjpeg62 is in slink!

All the gnome and imlib packages have moved to libjpeg62.  This was
arranged quite a while ago.  It was a fair amount of work to do,
because so many packages were interdependent.  I don't think we'll be
switching back.

Things are somewhat confused, because everybody didn't move to
libjpeg62-dev en-masse.  There are still lots of packages from before
libjpeg62 - I'm not sure if it's worth recompiling those.

I'd only be concerned about packages that have been linked against
both libjpegg6a and libjpeg62.  Currently, for i386, the following
packages have dependencies on both libjpegg6a and libjpeg62:


I'll file some bugs.

I now notice that there are a lot of packages that depend on Gnome
that are using libjpegg6a (yagirc, gmc, gnumeric, libgnome-perl,
balsa, gnotes, gtkicq).  These are getting linked against libjpegg6a
and libjpeg62 (try ldd).  That's bad.  That's evil.  I guess I'll file
some more bugs.

Horrible stuff.  I guess I should have put a dependency to
libjpeg62-dev in libgnome-dev.

For the other ports, it's going to vary depending on what -dev
packages the porters had installed.  For new recompiles, everybody
should be using libjpeg62-dev.  The libjpeg-dev and libjpegg-dev
packages should be moved to the oldlibs section.
