app-misc/gourmet-0.15.7 specifies dependency on <dev-python/sqlalchemy-0.6.4. If this dependency is still needed, then please report problem with app-misc/gourmet-0.15.7 + >=dev-python/sqlalchemy-0.6.4 to app-misc/gourmet upstream and add URL of upstream bug to this bug. If this dependency is no longer needed, then please fix dependency.
As stated in Bug #339415, there is a problem with sqlalchemy-0.6.4 which persists up to the gourmet-0.15.7 (just testet it). If the ebuild in the tree would be fixed accordingly ("!=dev-python/sqlalchemy-0.6.4" instead of "<=" or ">=", the problem for gourmet as well as for the updates would be gone.

Oops, looks like this originated with a (poor) attempt to fix bug #339415. Thanks for the report. Fix is in CVS. FYI Frank, a diff against the original with your changes would be easier to scan for the changes you made. I'm assuming it was just RDEPEND you changed.
