I guess you used:
camlp5o ./pa_log.cmo test.ml
If it is the case, this message happens because you specified no
pretty printer in the command line (there is no default pretty
printer).
In your "pa_log.ml" the expression
Eprinter.apply pr_expr Pprintf.empty_pc e
fails because of that.
Solution: use
camlp5o ./pa_log.cmo pr_o.cmo test.ml
