OK, I followed those steps and all the output .psc files came out  
looking fine, but the file "make_examples.out" shows the same error  
from ld on c, c++, f77, and f95: "ld: cannot find -lltdl" (and ld  
returns 1 as it did when I was trying my code).  I tried compiling my  
own code with this command as it appeared in the .out file:

/usr/bin/gcc sourcefile.c -o targetfile -Wl,-rpath -Wl,/usr/lib64:/ 
usr/lib64 `PKG_CONFIG_PATH=/usr/lib64/pkgconfig pkg-config --cflags -- 
libs plplotd`

but (unsurprisingly) I got the same error.

Additionally, the file "plplot_test.out" contained this:

Testing front-end c

So...what does this all indicate, and what's the next step?

Thanks for the help,
