[MLton-devel] Profiling under FreeBSD?

Is the profiling working under FreeBSD yet. I bootstrapped the compiler
from smlnj, but when I try to do profiles I get a lot of undefined
symbols in the linker phase:

sarah% mlton -profile true checksum.sml
/tmp/fileLupSBe.o: In function
`MLtonProfile52$$0xit_0$$1.L_76$$2.L_76$$Begin':
/tmp/fileLupSBe.o(]ext+0x485): undefined reference to
`MLton_Profile_Data_write'
/tmp/fileLupSBe.o: In function
`MLtonProfile57$$0xit_0$$1.L_61$$2.L_61$$Begin':

/tmp/fileLupSBe.o: In function
`MLtonProfile243$$0.main_0$$1.L_101$$2.L_199$$Begin':
/tmp/fileLupSBe.o(]ext+0x10da): undefined reference to
`MLton_Profile_installHandler'
mlton: call to system failed: gcc -o checksum /tmp/file5ivILK.o
/tmp/fileLupSBe.o -L/home/jlouis/mlton/lib/mlton/self -lmlton -lm -lgmp

Since I have absolutely no clue of what is going on yet, this is
something I would like to ask the audience about.

2nd question: Am I right about MLton using a stop-n-copy GC?
