There is a problem with the ebuild of the Enterprise Volume Management System (evms) that prevents it from bulding correctly.

ERROR: The ebuild did not complete successfully. !!! Function src_compile, Line 51, Exitcode 2 !!! compile problem My system is completely up-to-date (I did an emerge rsync ; emerge --update world before emerging evms), just to see if this problem had been rectified in a later ebuild of the package.
The problem is that gentoo-sources still use evms 1.0.1 driver source rather than 1.1.0. The user-space utilities are now at 1.1.0 and had dependencies on new data types defined in the 1.1.0 kernel headers. For 1.2.0 which is coming out soon, those dependencies on kernel headers has been elimintated so it would probably build but since the kernel components are as old as they are, it would cause the user-space tools to complain that the kernel side is not at the correct version required.
This is fixed with sys-kernel/gentoo-sources-r9 :)
Im disinclined to call this a BUG in the evms ebuild as it never *did* depend on a kernel-sources package; it was left as an task for the user to use whatever kernel she wanted to. The EVMS people are helpful, they include patches in the evms tarball against Linus kernels so you're never totally alone ;-) As Chavez points out, the end-user will be inconvenienced at run-time instead of build-time now, which isn't such a bad thing if you ask me... Ciao.
