I don't understand what the problem is. If you're using the standard
shebang line and use the first jifty in your path, everything does
work out right, no? Does OSX have a special bug I don't know about?

I have 159 scripts from CPAN installations in my $Config{bin} which
use the standard shebang line. I can use them all because they make
sure that they are run by the perl they were built with.

I never before realized that I have 4 scripts that use the env idiom.
Two of them use the wrong path to env anyway so are broken completely.
See what the two leftovers say:

No surprise for me because I did not use the first perl in my path to
build jifty. For me this is broken behaviour.

What happens for you if you let MakeMaker write the standard shebang line?
