./tclkit-linux-x86
% interp create i

% i eval package require vfs
can't find package vfs
vfs package pkgIndex.tcl needs something like this:
package ifneeded vfs 1.2 [list load "" vfs]
+ source on vfsUtils.tcl ..

You may have to do a "load {} vfs" first to make this work - there are
some loose ends
(incorrectly coded) aspects when MK is used in slave interpreters. Its mostly due
to my
ignorance about these matters - if you want to see it resolved, please bring it
up on the
Starkitmailing list - perhaps someone with deeper knowledge of Tcl will be able
to give
a hint on how to fix it.
