ruby18 not compiling on -CURRENT.... tr bug

[Sean McNeil]

Thanks, SANETO,

It was the bug in tr that was the problem.  I think this is a recurring
problem.  I recall tr had an issue once before and was fixed.

All is well again in my world :)

To recap, ruby18 was failing to portupgrade and ended up with an empty
config.h file.  SANETO saw the same issue and it is related to a bad
version of tr.  -CURRENT cvsup'd today has a fixed tr.

Cheers,
Sean
