    ./configure --with-libevent-dir=/usr/local

  rather than simply ./configure.

  If you have mysterious autoconf failures while linking openssl,

  consider setting your LD_LIBRARY_PATH to the openssl lib directory.

  For example, "setenv LD_LIBRARY_PATH /usr/athena/lib".

How to do static builds of tor:

Tor supports linking each of the libraries it needs statically. Use the

--enable-static-X ./configure option in conjunction with the --with-X-dir

option for libevent, zlib, and openssl. For this to work sanely, libevent

should be built with --disable-shared --enable-static --with-pic, and

OpenSSL should be built with no-shared no-dso.

If you need to build tor so that system libraries are also statically linked,

use the --enable-static-tor ./configure option. This won't work on OS X

unless you build the required crt0.o yourself. It is also incompatible with

the --enable-gcc-hardening option.

An example of how to build a mostly static tor:

./configure --enable-static-libevent \

            --enable-static-openssl  \

            --enable-static-zlib     \

            --with-libevent-dir=/tmp/static-tor/libevent-1.4.14b-stable \

            --with-openssl-dir=/tmp/static-tor/openssl-0.9.8r/ \

            --with-zlib-dir=/tmp/static-tor/zlib-1.2.5

An example of how to build an entirely static tor:

./configure --enable-static-tor \

            --with-libevent-dir=/tmp/static-tor/libevent-1.4.14b-stable \

            --with-openssl-dir=/tmp/static-tor/openssl-0.9.8r/ \

            --with-zlib-dir=/tmp/static-tor/zlib-1.2.5
