You still need and want the amd64 port. I thought you were talking
about adding rudimentary biarch packages to the amd64 port?

No. But the 64bit linker will give you stupid warnings about unknown
abis in all the 32bit libs and the 32bit linked will give you warnings
about the 64bit libs. Or it will link 32bit and 64bit code together
and totaly screw up.
And configure scripts will think libs are there even if they are only
there for the wrong arch and such stuff.

Haven't heard complains to the contrary yet.
