Thanks for trying this Alan.

PL_LIBRARY is the environment variable you can set (see tclAPI.c:
    static char initScript[] = 
    "tcl_findLibrary plplot 5.1 \"\" plplot.tcl PL_LIBRARY pllibrary";
).  Alternatively the 'pllibrary' Tcl variable can be set.

Basically 'PlbasicInit' needs to be able to find 'plplot.tcl' and source
it.  'tcl_findLibrary' is a standard Tcl command which simplifies this
task.

cheers,

Vince.
