Compile Error of Port dansguardian

[Scott N]

I am trying to compile Dansguardian to use and stress test DragonFly in 
our school but I get a compilation error about 5 seconds into the 
process.

DragonFly Kernel May 20th, latest Ports cvsup. Tried both dansguardian 
and dansguardian-devel and same error. I also contacted the ports 
maintainer and he was unfamiliar with the error at all and suggested it 
was a dragonfly problem. A search on Google also didn't help.

Here is the error or at least close (I am going from memory)

g++ -c .... ConnectionHandler.cpp
ConnectionHandler.cpp:50: istream: File not found

And then aborts right thereafter.

Any ideas why? I had compiled this port fine on a FreeBSD 5.1 install 
about 4 months ago fine without a hitch.


Thanks
