Building cfengine 3.0.0b1

I'm trying to build cfengine from cfengine-3.0.0b1.tar.gz downloaded
tonight.
I have 2 problems to bring to your attention:
1) net.c (and possible other files) is missing from that tarball.  This
causes
   the final link of cfknow to fail with lots of undefined symbolic
references.
2) in match.c lines consisting of 
   re_syntax_options |= RE_INTERVALS
   gave undefined symbols errors for both re_syntax_options and
RE_INTERVALS
   From some old messages (about AIX build problems) I suspect this is
because
   I have an old flex and/or bison. I ifdef'd the lines out and the file
compiled.

BTW, my version of gcc (which is 3.3.3 on Solaris-10) gives a warning
about -pthread

I am trying to build on a Solaris-10 system with either gcc 3.3.5 or
Sun's compiler Studio-12.0
