This information is not sufficient. dpkg spawns all kinds of
subprocesses, so you need to use the -f or -ff options to strace.
However, a better debugging method, at least initially, might simply be
to edit /var/lib/dpkg/info/xlibs.postinst and put the following at the
top of the script on a line by itself:
set -x
That will turn on the shell's debugging option.
