I confirm the problem here as well.  Only the first option is included in
the configure command output.

I know this is supposed to work so I tried it for the first time today, and
I confirm there are some problems.

Here is what I did.

*  Fresh checkout to plplot directory

*  cd plplot
cf/bootstrap.sh  #This is the step that Geoffrey missed, I believe

* mkdir ../buildtree
cd ../buildtree
../plplot/configure --srcdir=../plplot + other configuration options.
This configure seemed to work without any obvious problems.

* make
This step failed with the following message:
  gcc -DHAVE_CONFIG_H -I. -I../../plplot/src -I.. -I../include -I../include -I/us
r/include/freetype2 -I../../plplot/libltdl -g -O2 -mieee-fp -MT pdfutils.lo -MD 
-MP -MF .deps/pdfutils.Tpo -c ../../plplot/src/pdfutils.c  -fPIC -DPIC -o .libs/
pdfutils.o
../../plplot/src/pdfutils.c:36:21: plplotP.h: No such file or directory

Apparently we need some infrastructure in place so the internal PLplot headers
can be found in the source tree.  Rafael?

BTW, the autoconf documentation says the above --srcdir option is usually
not needed (since it knows where the configure script is located), and
indeed without it I got identical good configure results and bad make
results in a separate build tree.
