...which I didn't have, yet emerge reported success when it should have failed - there were no docs. I've copied libpng.so.2 -> libpng.so.2.1.0.12 from another (1.0rc1 stable partition) to /usr/lib/ and it's now building.
which versions of libpng do you have?
Just 1.2.5, plus what I copied. Although the thing built once it could see libpng.so.2, I couldn't find the KDE documentation in kdevelop-3.0_alpha2 (which didn't seem very usable so I unmerged it).
what is in settings->configure gideon->documentation tree->locateion of kdelibs documentation generated by doxygen? it should point to /usr/kde/3.1/share/doc/HTML/en/kdelibs-apidocs/. and then the documentation should be available in gideon.
Thanks - found it. I had no menubar but discovered that <ctrl-M> made it appear. Yes I do have KDE documentation now but had to use libpng.so.2
this is caused by graphviz which is linked against libpng-1.0.x. this bug is than the same error as bug #10726, so marking this as duplicate. *** This bug has been marked as a duplicate of 10726 ***
