I am trying to build SpamAssassin 3.0.2 on RH9 and it fails when I try to run make. The error message is:
<snip>
SHA1 object version 2.01 does not match bootstrap parameter 2.07 at /usr/lib/perl5/5.8.0/i386-linux-thread-multi/DynaLoa der.pm line 249.
SA 3.0.x requires Digest::SHA1 version 2.07 or higher, you've got 2.01, thus SA cannot build until you update Digest::SHA1.
