looks like bash-4.0 has broken semicolon escaping in subshells.  this comes up 
when using find's -exec like we do in a few places in eclasses:
                ls=$(find "$1" -name '*.po' -exec basename {} .po \;); shift
you can work around the issue in a couple of ways:
 - quote the semicolon:
	.... ';')
 - use backticks
	`find .... \;`

i'll tweak the eclasses to use quoting for now
