The newest version of the nvnet port (nvnet-src-20040813.tar.gz) won't build on FreeBSD 5.3R

[Bozhidar Batsov]

Here is the output from the the build:
===>  Building for nvnet-1.0.0274
"Makefile", line 7: Malformed conditional (${OSTYPE} == "FreeBSD")
"Makefile", line 7: Need an operator
"Makefile", line 13: if-less endif
"Makefile", line 13: Need an operator
make: fatal errors encountered -- cannot continue
*** Error code 1

I guess I have to edit the makefile, but I don't what changes it requires. Can
someone help me?
