In compiling gtkmm I get the following error. It seems that the atk dependency is missing. checking for glibmm-2.4 >= 2.4.0 atk >= 1.6.0... Requested 'atk >= 1.6.0' but ve rsion of Atk is 1.4.1 configure: error: Library requirements (glibmm-2.4 >= 2.4.0 atk >= 1.6.0) not me t; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
Thanks for the report, it's fixed in CVS now.
