- which version of Mac OS X?
- Which version of R? (version, architecture)
- Officially provided R or compiled by you? Official R is compiled with
Apple gcc.
- if R was compiled with Apple compiler, who knows what can happen if you
link with code compiled with a non Apple gcc?
- if the code runs ok on your supervisors iMac: did he use Apple compiler?
if so I wouldn't be surprised if your Macports compiler is a possible cause
of your troubles.
- on 64bit Mac OS X long int is 64bits and int is 32bits; on 32bit Mac OSX
both are 32 bits.
