This is odd. When you configure plplot, in directory plplot-961023, it
creates
directory tmp and makes symbolic links to the sources; then, make
proceeds in the
tmp directory.
The best way to restart, is to delete directory tmp and reconfigure.
Then, `cd tmp;make'

You could just comment these references to poll(); they are intended to
provide
a small (10 ms) delay. I will change that to select() in the future, or
just drop it.
This one is in the FGA.

This mean that you have not configured Tk, otherwise a libplplotdtk.xx
should appear.

You dont need to install to run the plplot demos; `make cdemos' links
against 
libplplotdX.so.4.99 in the tmp directory, so if you don't have
LD_LIBRARY_PATH set
to the tmp directory probably the library can't be found. try `ldd x01c'
and see were
it expect the library to be found. You can also try, in the tmp
directory
LD_LIBRARY_PATH=`pwd`:$LD_LIBRAY_PATH ./x01c

Please remember that plplot configure/makefiles/etc are a bit old, and I
have not
change anything. In fact, RLab uses plplot and advises to not using
shared libs.
However, I had no problems in using it in Debial Linux. As I don't use
Linux very
often, I am afraid I can't help much more.

Keep trying, and thanks,
Joao

PS: a correction to the FGA: in Linux I used gcc-2.7.2.3, and in SCO I
used egcc
