I just try to emerge endevour though it has no ppc-keyword. Everything seems to work fine except for the iBrowser component which displays everything correct in the thumbnail view. In the main view though it shows a negative of the actual image. ps: maybe it is an endianes issue (I've been told)
just commited endeavour-2.1.20-r1. this includes a patch that fixes images on big endian machines. i'm CC'ing sparc@gentoo.org on this, since i apply the patch to all big endian machines. i did not test this on sparc or sparc64. in theory it's needed and those ARCHs aren't KEYWORDSed anyway. closing.
