Thank you in advance for your help,

I suspect that the macro PTR is defined incorrectly in the installed
file udunits.inc, which I believe is included by readgeneral.f. On a DEC
Alpha, pointers are 64-bit entities and the corresponding Fortran type
is "INTEGER*8". See what the definition for PTR is in your installed
"udunits.inc" file and change it if necessary.  Then recompile
readgeneral.f.

Please let me know if this helps.
