Bug #124536 for Statistics-R-IO: subroutine redefined problem

Davor, I use Statistics::R::IO in order to run WeBWorK, an online homework system for math teachers. It is perl-based. I installed the R Statistics integration for WeBWorK, but ever since then WeBWorK gives this error message to my students: Subroutine fh redefined at (eval 1515) line 1. Subroutine server redefined at (eval 1516) line 1. Subroutine port redefined at (eval 1517) line 1. Subroutine _autoclose redefined at (eval 1518) line 1. Subroutine _autoflush redefined at (eval 1519) line 1. Subroutine _usesocket redefined at (eval 1520) line 1. The source for this error message appears to be Rserve.pm, where these subroutines are defined. Have you heard of this problem before; do you have a suggestion for a fix? Thank you!
