Michael,

this problem does not seem to exist anymore in the forthcoming 1.1
release ... in the 1.0.* releases it should work to use the
xotcl::interp command (which pre-initializes xotcl in the child interp)
instead:

 package require XOTcl

 xotcl::interp create Interp
 Interp eval {package require XOTcl}
 xotcl::interp delete Interp
