The problem is that paths are stacked in .pc files, so bindir is
${prefix}/bin, which isn't available or valid on a rootless install. A
solution would be to edit all paths to the corresponding path in
$goboLinks.

That would be possible, but would litter the goboPrefix (usually
$HOME) with /usr/bin etc links, as gobohide wont work on rootless.

Somewhere in the future $goboSystem/Links/{Executables,Libraries,...}
will be dropped and we will use $goboSystem/Index/{bin,lib,...}
instead. There is some code to switch to that layout already in the
tools, but I don't know how that would work on a rootless install, but
if it does FixDirReferences can use $goboIndex instead of '/usr' as
replacement.
Lucas can probably answer more on how goboIndex is enabled in the current tools.

Yes, it would be great if someone could magically just solve all problems ;)
If you like you can try the goboIndex approach. I'll try and answer
any question that may come up (hopefully quicker than this).
