The kavclient™ package is distributed in source form. It is available for free download from kavclient™ home page. To compile and install it on your system, follow these steps (common to all packages built with GNU autotools).

Besides the common configure options such as --prefix, kavclient™'s configure accepts one specific option: --disable-reentrant. It configures libkavclient to be built without _REENTRANT preprocessor symbol, which means it will not be suitable for multi-threaded applcations. If you are absolutely sure you will use libkavclient for single-threaded applications only, you can gain some very minor speedup by configuring it with this option.
