howto import define-report in account-piecharts.scm

[Larry Evans]

I tried to call gnucash from command line and then invoke the gnc:main 
program.
However, I got the following error:
<------- begin cut here -----------

I even tried adding:

(gnc:depend  "report.scm")

with the other gnc:depend's near the top of the account-piecharts.scm; 
however, I got
the same error.

Please, what should I do to get this to work?
