Ok, this was a nobrainer:
There is a slightly wrong path in imlib/files/patch-search-system-include-for-xshm.diff.
Please change "/usr/include/X11/extensions/XShm.h" to
"/usr/local/include/X11/extensions/XShm.h" (note the /local/ part in it) and
compile. This at least fixed the problem for my system :)
