Mail-SpamAssassin-4.0.0-RC1 -> Pyzor warn

[Avram-Teodor Berindeie]

I compiled Apache SpamAssassin -- Version 4.0.0-RC1 from sources and in the
testing phase I have the following problem.
When running the command:
/usr/local/src/Mail-SpamAssassin-4.0.0# spamassassin -t < sample-spam.txt >
spam.out
I get
Aug 29 20:27:42.299 [28229] warn: rules: failed to run PYZOR_CHECK test,
skipping:
Aug 29 20:27:42.299 [28229] warn: \t(Can't locate object method "new" via
package "Mail: [...]:SpamAssassin::SubProcBackChannel" (perhaps you forgot
to load "Mail::SpamAssassin::SubProcBackChannel"?) at
/usr/local/share/perl5/Mail/SpamAssassin/Plugin/Pyzor.pm line 336.
Aug 29 20:27:42.299 [28229] warn: )

It seems that it must be added to the respective file
use Mail::SpamAssassin::SubProcBackChannel;
immediately after line 37
use Mail::SpamAssassin::Plugin;
