Well, I'd say: there is no sane value you can assign to $T since you are
not allowed to write anything anyway:
"pkg_pretend must not write to the
filesystem." (http://dev.gentoo.org/~ulm/pms/4/pms.html#x1-9700010.1.2)
and since "pkg_pretend is run separately from the main phase function
sequence, and does not participate in any kind of environment saving" it
is not guaranteed to be set to the same $T later.
Cheers,
Tiziano
