these lines dont do what you intend as make flags are processed incrementally. i.e. the -j1 needs to be last, not first. dev-util/monodevelop-database/monodevelop-database-0.18.ebuild:16:MAKEOPTS="-j1 ${MAKEOPTS}" dev-util/monodevelop-database/monodevelop-database-1.0.ebuild:16:MAKEOPTS="-j1 ${MAKEOPTS}"
same issue exists with dev-util/monodevelop-boo
and dev-util/monodevelop-java
Cleaned out all the old junk.
