invalid read on Mac OS 10.6

[jzrake]

Valgrind reports an invalid read when loading shared object files. This seems to be independent of any lunar functions. Compile flags are:

export CFLAGS = -Wall -O2 -fPIC export SO = libtool -dynamic -lm

Error report is the same whether lua 5.1.4, or 5.2.0 is being used.
