Default re2c installation fails

Hi all,

I'm trying to upgrade my SpamAssassin installation. I've gotten as far as updating to p5-Mail-SpamAssassin-3.2.5_2 (from 3.1.1) along with its dependencies. On installation, it told me to run sa-compile. When I try to run sa-compile, here's what I get:

[root@shaunc p5-Mail-SpamAssassin]# sa-compile
[24063] info: generic: base extraction starting. this can take a while...
[24063] info: generic: extracting from rules of type body_0
100% [=========================================================================================================] 3662.83 rules/sec 00m00s DONE
100% [=========================================================================================================] 225.00 bases/sec 00m04s DONE
[24063] info: body_0: 679 base strings extracted in 4 seconds
cd /tmp/.spamassassin24063DuMmqktmp
cd Mail-SpamAssassin-CompiledRegexps-body_0
re2c -i -b -o scanner1.c
Can't exec "re2c": No such file or directory at /usr/local/bin/sa-compile line 287, <$fh> line 979.
command failed! at /usr/local/bin/sa-compile line 288, <$fh> line 979.
Sure enough, re2c doesn't exist on my system. So, off to /usr/ports/devel/re2c where I receive some errors:

[root@shaunc re2c]# make
[ snip configure output ]

I can't figure out what the problem might be. I've searched for various permutations of the dtor and virtual errors. I found one match for the error in basic_null_stream, but the post was in Japanese and didn't have any replies, anyway.

Any idea what might be going on? This is FreeBSD 4.11, gcc 2.95.4.
