On Solaris it is generally adviseable to duplicate all -L options (path to statically linked libraries) as -R options (path to dynamically linked libraries) as well. The resulting binary will find dynamically linked libraries without setting LD_LIBRARY_PATH.

For example, if linking against Oracle, libclntsh.so will be linked dynamically. This library is not in the standard system link path, but in $ORACLE_HOME/lib and will therefore not be found by a regular binary unless LD_LIBRARY_PATH is found. If compiled with -R$ORACLE_HOME/lib added to LIBS, this is not necessary and the binary will function without any special setup.

autoconf/configure should be fixed to create -R options for all -L options generated on Solaris.
