This should be fine since the current package path for Tcl will find 
these in /usr/lib{64}/tcl8.x.

If these are noarch packages, however, you should use /usr/share/tcl8.x. 
  Even though /usr/lib/tcl8.x is currently a symlink to 
/usr/share/tcl8.x, this may change in the future if we ever properly 
separate arch-specific and noarch packages.
