title: Multiple versions of Tcl
body: <p>Are there any particular things to think about when building and installing (globally) a new version of Tcl from source, besides relinking /usr/local/bin/tclsh and wish to the new versions?</p>
  
  <p>I know that the interpreter executables tclsh and wish are installed with different names, but what about the include and library files? When I build eggdrop, will it link with the latest version? How about the man pages - are the old ones overwritten by the new ones?</p>
