what's the current status of python-psyco package?

[Robert P. J. Day]

  once upon a time, there existed python-psyco.  and now, "yum
search" begs to differ.  on the other hand, there's this:

http://koji.fedoraproject.org/koji/buildinfo?buildID=72241

so is there a reason python-psyco is no longer part of the standard
fedora feed?

It is only available on i?86, so if you're running x86_64, it's not
available unless, I believe, you have the yum multilib_policy option
set to all.  It defaults to best, which only installs packages for the
arch you are running.

I take that last bit back.  The python-psyco package is not available
at all on x86_64, regardless of how may set multilib_policy. :)

  what's the reasoning for that?  is it because that package has no
value in a 64-bit environment?

The specfile¹ says:

# Upstream makes *heavy* use of inline x86 asm this would take extensive
# work to support anything other than x86. See the URL for more info.
# http://psyco.sourceforge.net/links.html
#
# """
# Here are a couple of non-Pythonic dynamic compilation projects. I am
# often pointed to them as potentials back-ends for Psyco, to help make
# Psyco portable beyond the current x86 machine code. However, I consider
# them as not really suited for Psyco.

A good scapegoat is almost as good as a solution.

It's a compiler, and porting a compiler to another platform means
re-writing large areas of code (at least the code generation part,
maybe some optimization parts...) Just compiling the present code
will result in a cross-just-in-time compiler, which still will generate
x86-code...

If you just want the 32-bit version, just get it from a 32-bit repo and
localinstall it?
