You'll have to translate everything in the spamassassin tarball's lib/ directory too.
Other factors to consider are where will you get equivalents for all the support libraries and utilities that SA uses. There's a LOT more to spamassassin than perl regexes. Some libraries that SA uses to consider include: Mail::SPF Net::DNS HTML::Parser DBI DB_File MIME::Base64 Mail::SPF IP::Country::Fast You'd have to convert all of those or find pre-made C equivalents.
