Are you using the ocamlbuild-based build system?

That would be my fault (I guess). See PR#3047. I haven't tested the
patch with the ocamlbuild-based build system, but I guess "initgroups.o"
and "setgroups.o" are missing from otherlibs/unix/libunix.clib... Could
you check that updating libunix.clib solves your build failure?

Add initgroups.o and setgroups.o in otherlibs/unix/libunix.clib, then
launch again the compilation.

It seems that -lm is missing in BYTECCLIBS and/or NATIVECCLIBS (see
config/Makefile). However, the ./configure script should have done this
for you. This might be worth a bugreport.

Please pay attention and don't mix both build systems: either use make
or ocamlbuild, but don't run make after having used ocamlbuild nor
vice-versa. To be sure, start from a fresh CVS checkout.

Seems to help but still bombs out.

   Ocamlbuild knows of no rules that apply to a target named ocamldoc/

BYTECCLIBS=   -lcurses -lpthread
NATIVECCLIBS=

This was all working fine before, ocamlbuild and make.

I don't mix and I always do 'make clean', 'make distclean' and './ 
build/distclean.sh'.
