Bugzilla Bug 50096

When emerging monodoc I got an version error about some mono support libraries
(gtk-sharp, gtkhtml-sharp, etc.) which is had obviously installed (through
dependencies). Though I couldn't find a gtkhtml-sharp ebuild.

After some googling and trying some emerge 'pretends' I found out that I needed
+gtkhtml in my USE flags. So... could the monodoc ebuild check if gtk-sharp has
actually been compiled with gtkhtml-sharp support built-in, and warn the user
if it is not?

Reproducible: Always
Steps to Reproduce:
1. Have gtk-sharp emerged without gtkhtml in your USE flags
2. `emerge monodoc`

Actual Results:  
Exact error is already scrolled from VT. 

Expected Results:  
Checked for gtkhtml-sharp support (in gtk-sharp package)

I have this same problem with 2004.1, portage 2.0.50-r8. When I try to emerge
monodevelop, it craps out at monodoc because it can't resolve the gtkhtml-sharp
module. (As the previous user reported.)

emerge monodevelop should yield a fully working monodevelop install where I can
compile and run C# programs inside of monodevelop.

I get this error too... but this is because I use Evolution 1.5 development
versions which install gtkhtml-3.1 instead of gkthtml-3.0.
So when I try to start monodevelop it craps out:

Unhandled Exception: System.DllNotFoundException: gtkhtml-3.0
in <0x00053> (wrapper managed-to-native) Gtk.HTML:gtk_html_new ()
in <0x0007d> Gtk.HTML:.ctor ()

/home/root/tmp/portage/monodoc-1.0/work/monodoc-1.0/browser/browser.cs:84)
Monodoc.Driver:Main (string[])

The things that bother me are actually these PORTAGE_TMPDIR strings in code...

Okay, i've just added a check for gtkhtml-sharp in the src_unpack function.
This is the best I can do until portage has support for USE variable based
dependencies. Marking LATER for when portage has that support.

Marking CLOSED, instead of LATER, as this is now resolved by the broken up
gtk-sharp components stuff.
