I found this same problem with PulseAudio, the problem is that the 0.40 series of intltool tries to parse configure.ac like it was a text file rather than a macro file; you *probably* want to restrict tests.
Created attachment 212135 [details] Build log
0.41.0 is now in Portage, please test it
+ 18 Feb 2010; Samuli Suominen <ssuominen@gentoo.org> + libcompizconfig-0.8.4.ebuild: + Raise intltool depend to 0.41.0 wrt #295819, thanks to Diego E. Pettenò + for reporting.
This bug is not fixed with >=dev-util/intltool-0.41 ! With >=intltool-0.41 and FEATURES="test" enabled, the ebuild does definitely not compile. I get the same error as seen in the log above. You maybe want to restrict the tests as recommended by Diego E. Pettenò.
I'll try to fix this later.
Tests are now restricted on libcompizconfig-0.8.4-r1. Thanks Diego for the report.
