!!! If you need support, post the topmost build error, NOT this status message.

As soon as nasm is compiled with -fno-force-addr, this package compiles. Please
add a strip-flag of -fforce-addr, or append -fno-force-addr.

you forgot to include the output from emerge --info.  please do that.

Not that I see any reason why it helps because the problem is already found,
but here you go:

Please know this is my make.conf, the error was for someone else, but I fixed
it with a bashrc entry.

nasm-0.98.39-r3.ebuild strips flags so that should fix things up.

Are you talking about the one released on 05 of january? If so I see nothing
about strip-flags in there..

Reponed as you haven't replied and I see no mention of strip-flags, nor
anything about flags in that ebuild.

resync.
