I run my own webwork server. I followed all the instructions to integrate webwork with R Statistics. Everything works fine, but now I (and my students) get annoying webwork warnings at the end of every page -- how do i get rid of them?

These subroutines appear to be defined in Rserve.pm. I found two copies of this perl module, one in usr/local/share/perl/5.22.1/Statistics/R/IO and one in opt/webwork/pg/lib -- for some reason, perl may be running over both of these copies. I have renamed

mv -v Rserve.pm Rserve.bak

in opt/webwork/pg/lib, and now it appears I don't get that error message anymore.

Yes, that's true, but it messes up other more serious things. I have reverted to Rserve.pm, and now I have the annoying error messages again. Any help? This must be a perl issue, where these functions are multiply defined.
