this needs either a DEPEND or a pre validating wether thie Phoenix/msession distribution is available or not. Otherwise, it looks like a gentoo related ebuild error: checking for msession support... yes checking for msession in default path... not found configure: error: Please reinstall the Phoenix / msession distribution
The PHP ebuilds now emit the following warning when USE=msession is set: * USE flag msession enables support for software not in Portage * * This ebuild will continue, but if you haven't already installed the * software required to satisfy the list above, this package will probably * fail to compile.
What about this: if useq msession; then if ! test -f /usr/include/msession/FOO.h; then die "msession USE-flag enabled. but no msession installed." fi fi or alike?
