Well, that's the bug, right? ;)
It uses what it's been built against, *if* that thing is actually
available (installed)--but it's easy to get into a situation
where that JS library *isn't* available because it's *not* installed--
and it's hard to hard to figure out that that's the reason *why*
the automatic proxy setting isn't doing anything: there's no Depends,
there's no Recommends, there's not even a Suggests, and there's not
even anything in the README that would even suggest `if you need
automatic proxy configuration to work, then you need to install
this javascript-interpreter library'.
I had to trace out the dependencies in Epiphany just to find that
libproxy was probably where I really wanted to look, and then I had to
go rummaging around inside libproxy to find that PAC-files were handled
by a module, and `pacrunner_mozjs.so' looked like it was probably
that module; and when I looked at that module with ldd, I got:
$ ldd /usr/lib/libproxy/0.3.1/modules/pacrunner_mozjs.so
linux-gate.so.1 => (0xb76f2000)
libmozjs.so.2d => not found
libplds4.so.0d => /usr/lib/libplds4.so.0d (0xb76d5000)
libplc4.so.0d => /usr/lib/libplc4.so.0d (0xb76d0000)
libnspr4.so.0d => /usr/lib/libnspr4.so.0d (0xb769c000)
libproxy.so.0 => /usr/lib/libproxy.so.0 (0xb7695000)
libpthread.so.0 => /lib/i686/cmov/libpthread.so.0 (0xb767c000)
libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb7656000)
libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7651000)
libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb750b000)
/lib/ld-linux.so.2 (0xb76f3000)
"libmozjs.so.2d => not found"? So then I went and found the package
that would provide that file, installed it, and everything 2 layers
up (like my web-browser) started working.
If we can't get a Depends, can we at least get a Recommends--or even
a Suggests?
Splitting the `pacrunner' module out into a separate package that Depends
on whatever it's linked against would be workable, too, I guess--
anything would be better than `find a developer who can read the source
and analyse the linkage'.
