Thanks everyone for the rpath suggestion. Since the current version of libz is so old, even Solaris probably has version 1.2.3.

Note that I tell it to look for zlib and jpeg in /usr/dist/share/..., but the

compiled binaries link against /usr/lib:

What evidence are you using to know that the compiled binaries link against /usr/lib?

If you are using 'ldd' to test which libraries are used, then it is important to know that on Solaris, the 'crle' command is used to set the default linker run-time search path (similar to ldconfig on Linux and FreeBSD). Unless a -R option was included in your build to hard-code the run-time search path for the library, the system's version may use a name similar enough that it will be used by default since it is in the linker run path and your library is not. If each library is installed in its own directory tree, then you should include a hard-coded run path. It looks like libtiff's configure accepts a '--enable-rpath' to automatically add a run-path at link time. Do 'man ld.so.1' to learn about the run-time linker.

Here is some sample output from crle:

% crle

Configuration file [version 4]: /var/ld/ld.config

   Default Library Path (ELF):    /lib:/usr/lib:/usr/openwin/lib:/usr/local/lib:/usr/sfw/lib
   Trusted Directories (ELF):    /lib/secure:/usr/lib/secure  (system  default)

Command line:
   crle -c /var/ld/ld.config -l /lib:/usr/lib:/usr/openwin/lib:/usr/local/lib:/usr/sfw/lib
