Thanks Joerg.

Curiosity struck my and I started looking at ftpcmd.y .I noticed that
there are a bunch of declarations immediately after the second `%%' in
ftpcmd.y.

If I move all those into the %{...%} block it builds on Linux. But I
dare not run this ftpd, since I have no idea what I'm doing with yacc :)

It's a hunch and it seems to build on Linux. But applying the same patch
on NetBSD causes the package to fail (even more miserably) on that platform.

Very curious to see what the answer to this issue is...
