Bugzilla Bug 166127

I was having trouble with an emerge of gnome-power-manager failing on a SGML to
man conversion step. Eventually traced to problem to the fact that I had both
app-text/docbook2X and app-text/docbook-sgml-utils installed and the
/usr/bin/docbook2man file as taken from the app-text/docbook2X which did not
work.

After "emerge -vCa app-text/docbook2X-0.8.7" and "emerge -va
app-text/docbook-sgml-utils" all worked as expected.


Reproducible: Didn't try

Steps to Reproduce:
1. emerge =app-text/docbook-sgml-utils-0.6.14
2. emerge =app-text/docbook2X-0.8.7
3. emerge =gnome-extra/gnome-power-manager-2.16.3

Actual Results:

Expected Results:  
Normal emerge results

Removing app-text/docbook2X-0.8.7 and remerge
app-text/docbook-sgml-utils-0.6.14 allows the emerge of
gnome-extra/gnome-power-manager-2.16.3 to complete.

There maybe other examples of of the difference between

Fix for the "fixed" docbook2X-0.8.7-r1.ebuild

Apparently, no one noticed until now that tacking on a ".pl" to everything
breaks the two scripts that actually need renaming.  Also, it renames the
utf8trans binary, which is compiled from C source, and sgml2xml-isoent which is
really a big sed script with a bit of shell wrapping it. I've fixed this by
only renaming the two files that actually collide.

Thomas, thank you, I've applied your patch (and fixed bug #205703). But next
time, please, open new bug to report new breakages.
