The version on bebits is pretty old at this point.

There is already a yasm optional package, just add "Yasm" to your
optional packages when building Haiku.

I have built a newer nasm on Haiku and it works fine. I apologize for
not updating HaikuPorts with my info, nor providing a binary package.
I'll try to do that soon.

There are indeed some incompatibilities with yasm's nasm support. When
I was porting dnetc I ran into several of these, and ended up having
to use nasm instead. Since then, the dnetc guys have fixed their asm
to be more compatible with yasm, and I will probably use it next time
I do a build. I believe they also reported that using yasm provided a
very slight speedup (or maybe it was actually the refactoring of the
crappy code :D). In any case, yasm supports 64-bit where nasm doesn't,
so it's probably a better choice to "standardize" on moving forward.
