rss2email broken by incorrect python version

[ArbitraryConstant]

I got this e-mail from my rss2email cron after upgrading from 8.04 -> 8.10 -> 9.04:

usr/share/rss2email/rss2email.py:222: DeprecationWarning: the md5 module is deprecated; use hashlib instead
  import cPickle as pickle, md5, time, os, traceback, urllib2, sys, types
/usr/share/rss2email/rss2email.py:233: DeprecationWarning: the mimify module is deprecated; use the email package instead
  import mimify; from StringIO import StringIO as SIO; mimify.CHARSET = 'utf-8'
/usr/share/rss2email/rss2email.py:188: DeprecationWarning: os.popen2 is deprecated. Use the subprocess module.
  i, o = os.popen2(["/usr/sbin/sendmail", recipient])
sendmail: fatal: Recipient addresses must be specified on the command line or via the -t option

Fatal error: sendmail exited with code 19200

I edited the last line of /usr/bin/r2e:

it said:

exec python /usr/share/rss2email/rss2email.py feeds.dat $*

I changed it to say:

exec python2.5 /usr/share/rss2email/rss2email.py feeds.dat $*

Now it runs without error and sends me my feeds via e-mail, which is the expected behavior.

The package should have python2.5 as its dependency, and should specify python2.5 if that's what it's written for.
