FWIW, the most robust way to handle this probably looks something like:
foreach $dir (@searchpath) {
$var = `dpkg --search $file`
do_stuff;
last if found;
}
That would seem to address the Hurd case (lib is available multiple times in
the search path due to symlinks, but only one of these files is known by
dpkg), while also eliminating collisions with similarly named files that are
not in the library search path at all (e.g., objects intended for use with
LD_PRELOAD or something).
The only requirement is that dpkg have an internal representation of the
library search path for the object type -- part of which comes from
/etc/ld.so.conf, part of which is hard-coded in ld.so. Oh... and then
there's RPATH...
