During 'emerge -uDN world' (using update-world script) I got this error: ----------------------- >>> Emerging (179 of 227) net-www/netscape-flash-10.0.12.36-r1 to / * flash-plugin-10.0.12.36-release.i386.rpm RMD160 SHA1 SHA256 size ;-) ...

there is no logic in rpm2targz to see if rpm2cpio is "ok", nor is it really feasible to test it. you easily get down a rabbit hole of crap. testing the exit value isnt usable either as you dont know why exactly it failed, and since the command is being piped, any incomplete output renders the process unusable. could perhaps just drop the rpm2cpio usage completely. i'm not aware of a situation where rpmoffset fails.
this was fixed as fallout of Bug 292057. rpm2cpio might be too old to detect compression in newer rpms, so just always use rpmoffset.
