These package recipes were modified for reason:
gtk+  : issue mentioned in this post, pulling in host glib
orc   : bad code in examples, honestly no idea how it built on Fedora
pango : add libxrender-native to DEPENDS_virtclass-native
perl  : change glibpth to reference Ubuntu 64-bit library paths
soci  : added configure.in.patch to correctly set SQLITE3_DIRS, as  
with orc, no idea how this built on Fedora

We took snapshot at beginning of 2011, last commit in git tree prior
to our mods is:

I realize this somewhat limits interest in this issue, hence my original
query to just better understand the build system and an idea of what I
should be looking at in terms of bitbake/openembedded dependencies.

This is tail-end of build log that fails, with last command-line  
issued from bitbake...

I am assuming the collision comes from...

libglib-2.0.so.0: symbolic link to `libglib-2.0.so.0.3200.3'

Host version of glib is newer than OE version and has g_bytes_unref.

What is not clear to me yet is why the OE bb recipe for gtk+-native is  
falling back on the host version of glib the first time through the  
build.
