GraphEnt is distributed both as pre-build executables for SGI and DEC Alpha OSF machines, and as source code for the other machines. The OSF executable is not linked with the CCP4 and PGPLOT libraries (the DEC Alpha OSF machine that I have access to is a molecular-biology-oriented GCG-running machine without a FORTRAN compiler, and I do not think I can convince them to buy one). If you have a DEC-Alpha machine and you compiled GraphEnt with CCP4 and PGPLOT support, I would be grateful if you could send me a copy of it, so that I can include it with the distribution.
