[racket-dev] Trouble building on FreeBSD 9.1

Hi,

When building Racket from source on FreeBSD 9.1, I get the following errors:

gcc -o racketcgc main.o  libracket.a libmzgc.a  -pthread -lm
-rdynamic -L/usr/local/lib -lffi
libracket.a(number.o): In function `sch_powl':
/usr/nick/git/racket/src/build/racket/src/../../../racket/src/number.c:3461:

libracket.a(number.o): In function `scheme_long_double_exp':

*** [racketcgc] Error code 1

I'm not sure what the problem is because the "undefined references"
should be included in the math library correctly referenced by the -lm
option passed to GCC.

Does anyone have any ideas or suggestions I can try?

Thanks,
Nick
