These packages get installed to a prefix that's determined at install time

They get installed to $VIRTUAL_ENV/etc
Binaries handle this by using paths relative to themselves.

$VIRTUAL_ENV/bin is prepended to $PATH.

The deafult ./configure options for execline seem to put everything in
$PREFIX/bin, which is on the PATH.
Those bits work.

I have a pretty extensive test suite for my system that's built atop s6,
and the only part that explodes is the access of leapseconds.dat

This feels counter to the "allstatic" strategy that s6 uses by default.
Would you be opposed to converting the leapseconds.dat to a .c format
during the build, and statically linking it?
