Hell yeah, I didn't know about this until I also had to build mongodb again. I'm doing the test as well and will lower the requirements asap ! Cheers mate

(check-reqs.eclass documents CHECKREQS_DISK_USR with "How much space in /usr is needed to install the package?".) What USE flags, CFLAGS, CXXFLAGS, LDFLAGS?

Ok then, just to be safe I will lower to 512M for DISK_USR when fixing bug #496196 (which should be pretty soon I assume). FYI: AFAIR mongodb pre-allocation consumes 2GB of disk space when you run mongod for the first time. I understand this can never be the case on some hosts where mongodb is just a dependency but I point this out here for the record.
Since bug #496196 is taking some time, I've done what I said in my comment above. +*mongodb-2.2.7 (17 Feb 2014) + + 17 Feb 2014; Ultrabug <ultrabug@gentoo.org> mongodb-2.2.6-r1.ebuild, + +mongodb-2.2.7.ebuild, mongodb-2.4.6-r2.ebuild, mongodb-2.4.7.ebuild, + mongodb-2.4.8.ebuild, mongodb-2.4.9.ebuild: + version bump fix #499864, lower user disk requirement to 512M wrt #495242 +
