[gmx-users] configure: error: cannot compute sizeof (off_t)

Dear experts,

I am still unable to overcome this error during the configuration:

configure: error: cannot compute sizeof (off_t)
See `config.log' for more details.

I came across this thread with the exact same setup as I have: 


I have tried uninstalling openmpi 1.4.4 and installing the more stable openmpi1.4.3 but I am still experiencing the same error.

./configure --enable-mpi --program-suffix=_mpi MPICC=/usr/local/bin/mpicc --with-fft=fftw3

I have also tried to explicitly provide the path to mpicc as above but it still gives me the same error.

This may or may not be relevant but at the end of the config.log there is also this line:

configure: exit 77

Does that mean anything?

Any help at all is appreciated!
