OK, that's all done. I got it to compile with that tip. Thanks!

The reason I was upgrading from 1.1.18 to 1.1.21 is that I hoped
it would fix a print quality issue that we have, but it didn't:

For a particular application, we grab images from an image display
program in X-Windows via xwd and convert them to PS and then send
them to a PS printer (Tektronix Phaser 840 or 850).

So the data path is either:

xwd | xwdtopnm | pnmtops

...or:

xwd | xwd2ps

Which one depends on whether or not netpbm is installed. netpbm is
preferred, since xwd2ps is a bit long in the tooth these days.

Anyway, once the PS output is created, depending on where the process
was initiated it will go to the printer one of two ways:

1) straight to the printer's LPD port.
2) through CUPS and then on to the printer.

If #1 is the case, the print quality is good. However, if #2, the
print quality is not too good, i.e. it is quite grainy. Could
this be caused by the /usr/local/lib/cups/filter/pstops filter?
If so, what I can do to improve the situation? Why does a PS
file need to be massaged by pstops in the first place?
