[LLVMdev] llvm-gcc build of inferno/plan 9 'mk' fails

[james northrup]

hello,

I'm attempting to build the inferno source tree using either of native
LTO or jit'd bins and having no obvious luck.

im using macports (current as of this email) llvm-2.5 and llvm-gcc on
a macbook pro (x86)

following the inferno directions verbatim will use 'cc' as the
compiler and just works.
the build tools are different from the naive build tools as follows:

CC="p llvm-gcc-4.2 `llvm-config --cflags` -march=i386  --emit-llvm -O0
  -c -I$PLAT/include -I$ROOT/include -I$ROOT/utils/    include"
LD="p llvm-ld `llvm-config --ldflags --libs all  `"
AR="p llvm-ar crvs"

any simplifications or rules of thumb that might help would be greatly
appreciated....

the build proceeds, finishes, and leaves me guessing:

suggestions?
 a) is macports known bad?
 b) am i missing the 'not reinvent the whole makefile for llvm
compilation' FAQ ?
 c) just missing a step?

the env is a mbp, with Xcode 3.1 and llvm-gcc installed, and macports
llvm/llvm-gcc installed and on the build-tools path
