Just a post with my progress in compiling GTK+-3.0.0.
It is fully compiled (and all debs in supplied link).
However, some conflicts are with stock libraries, specifically glib_2.34 (in glib_2.34_armel.deb) seems to not want to work nicely due to overwriting of a few system libraries.
These, should be able to work if the conflicting .so files are removed from the deb - as a test.

So, posting the debs here, in case they are usefull for anyone who wants to hack this also. At least it will save a sh-- load of compiling time having the debs.

Hopefully my weekend work can prove of shortly.

PS! A GTK+-2.90.0 is also in the tar file, but I dont work on that one.
