grep KEYW `equery which specimen`
KEYWORDS="-amd64 ~ppc sparc x86"

since its not just lacking amd64 entirely (this only seems to happen for obscure ruby packages), and has a specifically negative amd64, this means its broken. a quick run to, and search for specimen, reveals some updated ebuild for 0.5.1, and a comment: #-amd64: 0.4.5: int/pointer casting.

if you want to try installing it anyways, nano `equery which specimen` and change the -amd64 to amd64, emerge --digest specimen, and if it works, make a comment on the bug report that its fixed on amd64 (you proably want to grab the 0.5.1 ebuild before doing this)

64bit jackd can not talk to 32bit apps, afaik. you could run a 32bit jackd, and link with the other via UDP. or try the ALSA-lib plug:jack, or try using it in 64bit mode and figure out if theres any bugs ( SClang and PD would both require significant rewriting to work on 64bit mode due to their "VM"-y nature that expects ints to be the same size as pointers, but most everything else works fine )
