I assume you are having trouble with popen() in src/libes/gis. (I wrote
this a long time ago when we had trouble with a system supplied popen()
that didn't allow two or more simultaneous popen() calls.) If, in fact,
I solved this problem, I don't remember what the solution was.

However, we have since renamed this popen() to G_popen() and the
corresponding pclose() to G_pclose() and modified the routines in the
gis library to call these instead.

Note: I would very much like to know why you are getting this error.
Have the arguments to popen() changed, or is this die to the fact that
the gis library has its own version of popen() which overrides/conflicts
with the system supplied popen()?
