[pstricks] Drawing normal curve

[vkanetka at uoguelph.ca]

Herbert:

I am using pst-func to draw normal distribution and following example
from documentation. There must be something wrong with my set-up because
I am getting following error message.

%%[ Error: undefined; OffendingCommand: Euler ]%%
%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

My example and list of files follows:
