Another form of compression is offered using the LZO library.
If this library is not installed, you wil get an error when running the configure script. You can either install the LZO library, or disable support for LZO compression by using the "–disable-lzo" option when running the configure script. Note that if you disable support for LZO, the resulting binary will not work correctly on VPNs where LZO compression is used.
You can use your operating system’s package manager to install this if available. Make sure you install the development AND runtime versions of this package.
If you have to install lzo manually, you can get the source code from http://www.oberhumer.com/opensource/lzo/. Instructions on how to configure, build and install this package are included within the package. Please make sure you build development and runtime libraries (which is the default).
