Tom,

I took you up on your offer to logon to your system.  I made a change
to the user 'mcidas's .cshrc file which I describe below.

The changes I made to your .cshrc file area:

o add definition for McINST_ROOT
o changed PATH so that /usr/bin came before /bin
o adde definitions for CC, CPPFLAGS, CFLAGS, FC, FFLAGS
o commented out sourcing of GEMPAK environment file, Gemenviron

The last action was the one that was causing your problems.  What happens
when you do something like 'which echo' (a sequence in
~mcidas/mcidas7.6/src/mclog) is .cshrc gets reread.  The sourcing of
Gemenviron was causing the line:

Setting to decmaps

to be emitted BEFORE the results of the action.  For instance, a:

which echo

would result in:

Setting to decmaps
/usr/bin/echo

The logic in the McIDAS build/install scripts traps this output and
looks for echo.  Since it gets the first line, no echo is found and
the script exits.  Without the source of Gemenviron (which is not needed
nor wanted for the 'mcidas' account), all that gets emitted from a
'which echo' is '/usr/bin/echo'.  The build will proceed normally now.

>Thanks.

You are welcome.
