I was trying to compile kopete 0.6.2 and I get this error

checking for size_t... no
checking size of size_t... 0
checking for unsigned long... no
checking size of unsigned long... 0
checking sizeof size_t == sizeof unsigned long... no
configure: error:
Apparently on your system our assumption sizeof size_t == sizeof unsigned long
does not apply. Please mail [email protected] with a description of your system!


Anyone know how to fix it or know how to get kopete working?
