OK, I suppose this could be a nice feature. Do you think it would be
terribly complicated?

Well, I'm probably just messing things up. Here's what I have. The .so's
are in /home/foo/lib. libqt.so is definatly there.

(gdb) set solib-search-path /home/foo/lib
(gdb) b main
r
Breakpoint 1 at 0x80af805: file main.cpp, line 469.
(gdb) r
main-program: error while loading shared libraries: libqt.so: cannot open shared object file: No such file or directory

Program exited with code 0177.
(gdb) set solib-search-path /home/foo/lib
(gdb) r
main-program: error while loading shared libraries: libqt.so: cannot open shared object file: No such file or directory

Program exited with code 0177.
(gdb)

However, If I set the LD_LIBRARY_PATH it works. I'm using GDB 6.1 which
is rather old. I suppose I should upgrade.
