 SUSE 9.3, 10.1, 10.2, or 10.3, SLES 9 or 10, CentOS 5, Scientific Linux 5
   (Fedora Core 5 should continue to work but is deprecated.) 

2) If necessary update to the current LONCAPA-prerequisites (1-10), and 
replace gnuplot_loncapa with gnuplot 4.2. Note: if you already updated to 
2.6.0, 2.6.1, or 2.6.2 you will have already done this so you can skip this 
step.

Fedora 7 and 8, it is assumed this occurred previously during the original
installation.

yum update --obsoletes 

(b) RedHat Enterprise 4 

up2date -u LONCAPA-prerequisites
up2date -i gnuplot 

(c) Red Hat 5/Centos 5/Scientific Linux 5

Use yast-> Installation Source to refresh the LON-CAPA repository
Use yast->Software Management->Search to update LONCAPA-prerequisites (to 
version  1-10), install gnuplot and delete gnuplot_loncapa. 

On all distributions, it is recommended that you check that you have the 
correct versions of LONCAPA-prequisites and gnuplot installed before 
proceeding. 

rpm -q LONCAPA-prerequisites
rpm -q gnuplot
