Created attachment 395100 [details] build log The compilation fails at this line: ../x2goclient-4.0.3.1/onmainwindow_privat.h:88:21: fatal error: X11/xpm.h: No such file or directory 'xpm.h' could be provided by x11-libs/libXpm but it's not in the dependencies of x2goclient.
Upstreams lists 'libxpm-dev' as a build-dependency for the debian packages: http://code.x2go.org/gitweb?p=x2goclient.git;a=blob;f=debian/control;h=becd4bc7c6bb38f4e9fc3fc6acb5a724b890a00b;hb=fd1151e48ad325c18857f1d3daceb5b8e5edda9d
And it had been in the list for some time, thanks for catching and reporting this! Fixed in all current ebuilds
