Hum, I don't think it's the reason for the problem there.  
LD_LIBRARY_PATH only affects runtime, and MAIN__ the main Fortran  
program as generated by the compiler.

Is your main program Fortran or C code? if it's Fortran, make sure  
the corresponding object file is indeed included in your final  
linking command-line. If it's C code, try linking with "gcc - 
lgfortran" instead of "gfortran".

Hope this helps, and please report back to us with this information  
if you need further advice.
