Output from configure: checking for wxWidgets version >= 2.8.9... no (version 2.8.7 is not new enough) configure: error: wxWidgets must be installed on your system but wx-config script couldn't be found. Please check that wx-config is in path, the directory where wxWidgets libraries are installed (returned by 'wx-config --libs' command) is in LD_LIBRARY_PATH or equivalent variable and wxWidgets version is 2.8.9 or above.
Thanks for the report, I've bumped the wxGTK dependency in the ebuild to >=2.8.9 Fixed in CVS
