Comment(by markwright):
Replying to [comment:14 simonmar]:
@markwright: will this work when the libraries are in the build tree, or
only when installed?
Only when they are installed (where it works great, I built 170 pkgs from
hackage using in the Gentoo Haskell overlay with 7.7.20121102 using this
patch with no LD_LIBRARY_PATH).
In the build tree it can not find the libraries (of course a workaround
would be to set LD_LIBRARY_PATH):

Some thought needs to be put into how to manage shared libs on the various
platforms we support. Sadly the solution is likely to be different on
Windows vs OSX vs ELF-format platforms. For ELF platforms our current idea
is to put all shared libs in `/usr{/local}/lib` with names like
`libHSfoo-x.y.z-ghc-a.b.c.so`. Having them all in the system dir like that
has it's downsides and it does not work for per-user installs. If we want
to have multiple instances of the same version of a lib then it's even
more problematic.
All ELF linkers support the RPATH/RUNPATH mechanism for executables and
shared libs to locate each other without them having to be on the standard
linker path. This basically involves embedding the path in them at link
time. It must be acknowledged that some linux distributions eschew the use
of rpath for various reasons. We must take that into consideration. Also
we must consider relocatable/redistributable binaries...
The GNU and Solaris linkers support an extension which allows the above
mechanism to work, even for relocatable binaries (so long as the libs are
kept relative to the executable). Basically one can set an rpath that uses
`$ORIGIN` and at runtime the `$ORIGIN` is substituted for the file system
location of the executable or shared lib in question.
Note that on Linux at least the `$ORIGIN` is always passed by the kernel
so that the dynamic linker can resolve it. See the attached program which
demonstrates this.

Comment (by duncan):
Should have linked to the docs for `$ORIGIN`:
Solaris:
http://docs.sun.com/app/docs/doc/805-3050/6j2tng0mg?l=koa=view
Solaris and Linux:
http://www.scons.org/wiki/UsingOrigin
GNU man ld.so
{{{
$ORIGIN and rpath
ld.so understands the string $ORIGIN (or equivalently ${ORIGIN}) in an
rpath specification (DT_RPATH or DT_RUNPATH) to mean the directory con‐
taining the application executable. Thus, an application located in
somedir/app could be compiled with gcc -Wl,-rpath,'$ORIGIN/../lib' so
that it finds an associated shared library in somedir/lib no matter
where somedir is located in the directory hierarchy. This facilitates
the creation of turn-key applications that do not need to be
installed into special directories, but can instead be unpacked into
any directory and still find their own shared libraries.
}}}
This may also be useful for binary distributions of ghc that use shared
libs.
