	OK. Can you post here DEFS variable you can find in src/Makefile. It is 
like :

DEFS = -DHAVE_CONFIG_H -Dd_version_rpl=\"4.00pre8x\" \
         -Dd_exec_path=\"${prefix}\" -DFORCE_GNUPLOT_PATH -UDEBUG \
         -DMOTIF_SUPPORT -DPOSTSCRIPT_SUPPORT -DGNUPLOT_SUPPORT \
         -DVIM_SUPPORT -DMYSQL_SUPPORT -UEXPERIMENTAL_CODE $(date) -g

I think you have build gnuplot and RPL/2 with DFORCE_GNUPLOT_PATH and 
RPL/2 cannot find any gnuplot executable.

	In CLI, gnuplot persists until you leave RPL/2. In script mode, you 
have to use PERSIST if you want to detach gnuplot from RPL/2.

	PR1 prints the first stack level. PRLCD prints gnuplot graphic.

	Please report here DEFS and gnuplot path.
