t/op/spawn.t: failure due to Perl 5 problem

[jkeenan]

On a linux/i386 box to which I have some access, I try to test Parrot as much as possible. On this box, the system Perl is 5.10.0 (some level of Ubuntu) but I use 5.12.0 compiled from source.

I've recently noticed this failure during make test (configured with no options):

t/op/spawnw...............Perl lib version (5.10.0) doesn't 
  match executable version (v5.12.0) at 
  /usr/lib/perl/5.10/Config.pm line 46.
Compilation failed in require.
BEGIN failed--compilation aborted.
^Cmake: *** [op_tests] Interrupt

And at this point, make test stops dead.

For reasons I cannot fathom, this test plays around with env. When I remove this nonsense, t/op/spawnw.t PASSes completely.

Would anyone object to my applying this patch before 3.3?

Thank you very much.

Eliminate us of 'env'

Comments? Can this go in before 3.3?

Thank you very much.

It can go in and it did, as 73edd4957. Thank you for the fix.
