[mythtv] Error while building MythMusic

[Starkeeper]

I installed all required libs and so on, but everytime I try make I get
theese errors:

What's wrong?
It seems to me that this is a basic C error. Cause 'srand' is a standard
function. But all libs and so on where installed and working. I made many
apps before with this configuration.
