- on a 'standard' installation of linux distribution, there is no 
fortran 90 compiler. You have to instal one, either intel, or portland 
or g95...

- you can compile on another similar machine, but, you must check that 
you have the same version of the C librairies.

- If you want to compile for a parrallel execution of the code, you must 
have the mpi libraries intalled on the computer where you compile the 
code, lam-mpi in your case. If not, you will only be able to produce a 
serial version of the code
