PPM packages for Tk-804.031 (for both 32-bit and 64-bit builds of Win32 perl) have now been added to the sisyphusion repo.

ppm install http://www.sisyphusion.tk/ppm/Tk.ppd --force
[download]

The 32-bit builds passed all tests, but the 64-bit builds failed (with segfaults) on 2 of the test programs:

t\create.t                 (Wstat: 65280 Tests: 271 Failed: 1)
  Failed test:  270
  Non-zero exit status: 255
  Parse errors: Bad plan.  You planned 543 tests but ran 271.

t\zzTixGrid.t              (Wstat: 768 Tests: 33 Failed: 0)
  Non-zero exit status: 3

(Same result when building with Strawberry Perl.)

Ray Smith, if you want to build Tk yourself for ActivePerl, you can do it with Strawberry Perl - but only if your Strawberry Perl and ActivePerl have the same perl version number and archname (perl -V:archname).
If they match on both counts, then the Tk-804.031 that you build with Strawberry Perl, will work quite well with ActivePerl - though it will probably require that strawberry/c/bin is in your path.

Cheers,
Rob
