Thanks. I managed to make it working for me (32 bit, gcc4+). But I needed to add path to xorg-macros to every autogen.sh because macros directory is packagefs managed and read only (I don’t know much how Autotools work and how to deal with it). Also I needed to create symlink for libXaw.so.7 because it is only present in develop directory.
Surprisingly many X11 libraries are already present in HaikuPorts.
