All automated tests pass for me on linux. For solaris/Sun's LD, I had to:

in order to make dll_path and library_chain pass. I'm not sure why this 
is necessary. The test were passing as of boost-04-10-16-0000+gcc_sun_patch.

Note that the following also works:

This is my understanding of the problem so far:

1) linker search path
Used at link-time only
2) runtime/dynamic linker search path
Recorded at link-time to be used at run-time.
3) linker search path for emulating runtime behaviour
Recorded at link-time to be used at link-time, when a shared
library needs to be searched for.

GNU's ld has
1) -L
2) -rpath (or -R)
3) -rpath-link first, then -rpath, then (on solaris) -L
SUN's ld has
1) -L
2) -R
3) -L or -R (not sure in which order)

Best,
