Might or might not - I haven't tried it for many months...

?  What's that export PATH error?  Hmm, do I have a typo somewhere?

Right, in fact, ptxdist as of that date didn't understand x86_64 at
all.  I'm not sure even if current ptxdist does.

Right, you need to crosscompile termcap yourself.
Note, however, that back then I found the easiest way
to install termcap was to install ncurses instead.
Have a look at ptxdist-testing-20031113/rules/ncurses.make.

Ptxdist-0.6.0 has an actual termcap; have a look at
ptxdist-0.6.0/rules/termcap.make.  You can download that
at ptxdist.sf.net.

Good luck!  Oh, also, please use crosstool-0.28-rc37 (or whatever's latest)
instead of crosstool-0.27.
