 Arnold K. Pizer - Note on upgrading to WeBWorK 1.9  7/25/2003; 9:06:58 AM (reads: 1155, responses: 2) If you are already running WeBWorK 1.8, the only additional software required for WeBWorK 1.9 is the perl module HiRes.pm. To install this as root run the command: # perl -MCPAN -e shellcpan> install Time::HiRescpan>exit Before runing the above command, Red Hat 9 users should, as root, run # unset LANG since otherwise the installation of Time::HiRes will fail due to unicode issues. If you are running WeBWorK 1.7 or an earlier version, you will also have to install dvipng. For this see the instructions in "Installing WeBWorK on a Linux System" and "Installing WeBWorK on a Red Hat Linux 9.0 System". Arnie <| Post or View Comments |>

Try the installation and if it fails, do a Google search with the error message, HiRes etc. If the error message mentions "missing separator", then I would try the "unset LANG" hack first.
