If you are truly + paranoid about security, you should use static libraries. +* you use the GNU libtool code during linking + (http://www.gnu.org/software/libtool/libtool.html) +* you use pkg-config during linking (this requires that + PKG_CONFIG_PATH includes the path to the OpenSSL shared + library directory), and make use of -R or -rpath. + (http://www.freedesktop.org/software/pkgconfig/) +* you specify the system-wide link path via a command such + as crle(1) on Solaris systems. +* you add the OpenSSL shared library directory to /etc/ld.so.conf + and run ldconfig(8) on Linux systems. +* you define the LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH (HP), + DYLD_LIBRARY_PATH (MacOS X) or PATH (Cygwin and DJGPP) + environment variable and add the OpenSSL shared library + directory to it. + +One common tool to check the dynamic dependencies of an executable +or dynamic library is ldd(1) on most UNIX systems. + +See any operating system documentation and manpages about shared +libraries for your version of UNIX.
