Hello Vince,

I have done one additional interesting experiment with pltcl.  I forced it
to *not* work by temporarily changing the /tcl string to /tclx in tclAPI.c.
Here is the resulting error message:

/usr/local/plplot/bin/pltcl
application-specific initialization failed: Can't find a usable plplot.tcl
in the following directories:
    /usr/lib/plplot5.1.0/tclx /usr/local/plplot/lib/plplot5.1.0/tclx
/usr/local/lib/plplot5.1.0/tclx /usr/local/plplot/library /usr/local/library
/usr/local/plplot5.1.0/tclx/library /usr/plplot5.1.0/tclx/library

If I change tclx back to tcl, then this works because the required file
is in  /usr/local/plplot/lib/plplot5.1.0/tcl.

However, you will note the interesting difference with the previous error
message. Instead of looking in /usr/local/plplot/lib/plplot5.1.0/tcl like
pltcl, plserver is looking in ./lib/plplot5.1.0/tcl.  Howcum?  It's
executing in the /usr/local/plplot tree not the . directory, and one of the
clues tcl_findLibrary is supposed to use to get the tree prefix is the
location of the executable.  Also, one error message starts with a different
header "(*AppInit)" rather than "application-specific initialization failed".
Is that significant?

Hope this extra information helps you get this straightened out.
