>Description:
ftp://ftp.kame.net/pub/kame/misc/qpopper-4.0.5-ipv6-20030313.diff.gz, which is applied by mail/qpopper, has the following lines (for patching popper/
main.c):

...
+#ifndef INET6
         unsigned long  a = addr;
+        unsigned short n = ntohs ( port );
         unsigned short n = port;
         char           b [ 25 ] = "";
+#endif
...

this leads to n being defined twice and thus the compilation to fail.

>How-To-Repeat:
compile mail/qpopper without IPv6 support.

>Fix:
I would assume that the developers of the patch forgot to cancel out the original line (unsigned short n = port;). So a quick fix might be just to patch it away with an additional pkgsrc patch to popper/main.c (it is being patched anyway for other things).
On the longer run, it would be probably better to correct the IPV6 patch. Does anyone know how to report this to its author(s)?
