That seems fine... although I have only used valgrind on 32 bit apps,
can you try building Roxane as a 32 bit executable and see if that works better?

Also, how did you get and build your copy of valgrind?

It's not fine, it's a 64-bit executable but by default Valgrind-on-Mac
only handles 32-bits.  (This is because OS 10.5 builds everything as
32-bit by default, even though it's 64-bit capable.)

You can either build your executable as 32-bit, as Dan says, or
configure with --target=amd64-linux.  If you do the latter it may not
work, as it hasn't been tested for a while.
