I have revision 1.2 of the mtd-utils-20100718 ebuild incorporating the parallel build patch. Nevertheless it failed to build with both MAKEOPTS="-j1" and with MAKEOPTS="-j3". The first directory the make enters is the ubi-utils subdirectory, and it fails while linking the ubiupdatevol program because it cannot find -lmtd. I'll attach the build log for the MAKEOPTS="-j1" case as it's shorter.

Created attachment 239653 [details] Build log for MAKEOPTS="-j1" case.
If I remove the src_prepare() section of the ebuild (removing the parallel build patch) and use "emake -j1" in the src_compile() section, then it builds with no errors.
