== Modulefiles ==
==== 8.6.1 version of Tcl built from /usr/local/src ====
Although the [[PCLinuxOS]] 64-bit repositories include Tcl they do not include a development package with the configuration files required to build Environment Modules on Linux from source. Building Tcl from source will make the required files available.<ref>{{cite web | url=httphttps://sourceforge.net/projects/tcl/files/Tcl/ | title=TCL - Browse /TCL at SourceForge.net }}</ref>
