Looks like it "knows too much" about what X $DISPLAY looks like and is
tripping over the launchd socket (specifically, removing the leading
slash). This is a sadly common bug; programs should not make assumptions
about what $DISPLAY looks like, but too many do (mostly as a long obsolete
workaround for issues with ancient versions of X11, around the R2 or R3
days).

It's not clear from this whether it's the Perl module or cssh that is
breaking $DISPLAY.
