Bugzilla Bug 61134

When trying to emerge scilab-3.0, the build fails complainig:

checking if gtk is version 2.1 or later... 2.4.4
Package libgtkhtml-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgtkhtml-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgtkhtml-2.0' found
checking for html_document_open_stream in -lgtkhtml-2... no
configure: error: Could not find the libgtkhtml-2.0 package.

!!! ERROR: app-sci/scilab-3.0 failed.
!!! Function econf, Line 362, Exitcode 1
!!! econf failed

libgtkhtml is on the system (Version 3.0.10-r1), and the /usr/lib/pckconfig 

Reproducible: Always
Steps to Reproduce:
1.ACCEPT_KEYWORDS="~x86" emerge scilab
2.
3.

Actual Results:  
Build fails with the message above

Expected Results:  
Should emerge cleanly

I'll attach emerge --info output and the emerge log to this bug.

emerge --info output

One shouldn't pres enter to fast ;)
It should be:

libgtkhtml is on the system (Version 3.0.10-r1), and the /usr/lib/pkgconfig
folder contains libgtkhtml-3.0.pc .. but not 2.0 ...

Maybe scilab absolutely requires libgtkhtml version 2. Check if you have 
"libgtkhtml-2" installed (emerge -p =libgtkhtml-2*). If not, please install it 
then try to install scilab again.

I have both 2 and 3 versions of libgtkhtml:

aconite scilab # emerge -Cp libgtkhtml

>>> These are the packages that I would unmerge:

 gnome-extra/libgtkhtml
    selected: 2.6.2 3.0.10-r1
   protected: none
     omitted: none

From my log of compiling scilab, it looks like it needs the version 2:
aconite portage # cat 4249-scilab-3.0.log  | grep gtkhtml
checking for html_document_open_stream in -lgtkhtml-2... yes
gcc -O -Dlinux -fwritable-strings -DNARROWPROTO `pkg-config gtk+-2.0 --cflags` -I/usr/include -I/usr/include  `pkg-config libgtkhtml-2.0 --cflags` -c helpbrowser.c

Had just libgtkhtml 3 installed. After pulling in version two scilab installed
fine, so you're probably rigth about scilab absolutely requireing libgtkhtml
version 2.
So changing the depencies in the ebuild should fix this.

Fixed in Portage. Thanks for reporting and for the feedback.
