IBM Risc migration

Hi all,
I have been dealing with the following problem one week now without any progress.
I've a source code written in C which is using X libraries in order to create a graphical interface to visualise results produced by another code written in Fortran.
The README file of the C code says clearly that it is written only for IBM Risc 6000 machines.
Does anyone know if this code can run on any other unix/linux platform.
I have to add that the makefile uses the xlc compiler made by IBM for certain IBM platforms.
My feeling is that this code is impossible to run somewhere else.
Is it correct?
I appreciate any feedback because I have DEATH-lines (deadlines0 to respect

Without knowing exactly:
IF the author explicitly states for IBM Risc - I would take his word for it.
What he is talking about is the grphics rendering routines, not necessarily the routines that read FORTRAN library output from a file.
If you're on Linux there are loads of goodies like gnuplot that can do this kind of thing.

thanks for the reply!!
the problem is that there are not output files between fortran and C. The entire procedure is dynamic, which the fortran code asks the user if he wants a plot of the results not only in the final stage but also in intermediate steps. If the answer is yes a dynamic link is activated and the data go to the C graphic library...
So I cannot use GNUplot in this case but only the integrated C environment which is not compatible with my system.
