To compile the userspace programs in the Open vSwitch distribution,
you will need the following software:
- - A make program, e.g. GNU make. BSD make should also work.
+ - GNU make.
- The GNU C compiler. We generally test with version 4.1, 4.2, or
4.3.
- - pkg-config. We test with version 0.22.

- libssl, from OpenSSL, is optional but recommended if you plan to
connect the Open vSwitch to an OpenFlow controller. libssl is
required to establish confidentiality and authenticity in the
(On Debian "lenny" the above can be installed with "apt-get install
python-json python-qt4 python-zopeinterface python-twisted-conch".)

before you run the testsuite. You do not need to install Open vSwitch
or to build or load the kernel module to run the testsuite. You do
not need supervisor privilege to run the testsuite.

Sometimes a few tests may fail on some runs but not others. This is
usually a bug in the testsuite, not a bug in Open vSwitch itself. If
