I haven't used CXML but I have done a lot of FORTRAN.

As far as I understand it, language specific runtime libraries including the
FORTRAN one come with the base operating system and do not normally show up
separately in $ PRODUCT SHOW PRODUCT.

In VAX days, the relevant file was SYS$SHARE:FORRTL.EXE.  On Alpha, it looks
likely to be SYS$SHARE:DEC$FORRTL.EXE, however, it may not be quite that
simple as there are also other translated images present which may be accessed
using a logical name - $ SHOW LOGICICAL *FORRTL*

Try writing a Hello World FORTRAN program.  If that runs ok, your FORTRAN
runtime library is at least present and you probably need to concentrate on
finding a newer version.

If you have the extended message help installed, $ HELP /MESSAGE
may give you some helpful hints about whatever error message you are getting.
