SystemRequirements

Essential

1. RScheme version 0.7.3.4-b8 or above

   On debian don't forget to install the required -dev packages, e.g., zlib1g-dev for compressed repositories.

   There's a port to Chicken Scheme (chicken 4, aka hygienic chicken) on the way; but not yet ready to be released (we need some basic fixes in chicken until it handles the load).

2. OpenSSL. (Used to be semioptional; Askemos works with degraded security for humans who are not allowed, to use cryptography and signatures. However the current build depends on it. Will become optional again.)
3. PostgreSQL client library.

4. MySQL client library from http://www.mysql.com/ . Tested with version 3.23.43-3 to 5.0.18 (TODO make this a configure time option).

5. sqlite3 library version 3.3.8 or above
6. The pcre library from with utf-8 support enabled (TODO make this a configure time option).
7. libmagic
8. A ntp server http://www.ntp.org (nodes need resonable synchronized time). optional recommended
