texlive lists dependencies in the tlpobj file (and texlive2pkg will pull
them out and list them in the Makefile it produces) but it typically
doesn't do a very complete job of it.  So when packaging I'll also look
for "\RequirePackage" in the source and generally add dependencies based
on that.

However in the xcolor case colortbl is an optional dependency, it is
only required if the "table" option is given. There is also an optional
dependency on tex-oberdiek (for pdfcolmk.sty) if the "fixpdftex" option
is given.
