Description solar (RETIRED) gentoo-dev 2006-12-01 13:57:18 UTC 
The dhcpcd-3.x versions are using what appear to be non SuSv3 functions which are not supported by atleast uclibc and probably others.
The exact error is as follows.

interface.c:43:21: ifaddrs.h: No such file or directory
interface.c: In function `read_interface':
interface.c:99: warning: implicit declaration of function `getifaddrs'
interface.c:102: error: dereferencing pointer to incomplete type
interface.c:104: error: dereferencing pointer to incomplete type
interface.c:107: error: dereferencing pointer to incomplete type
interface.c:108: error: dereferencing pointer to incomplete type
interface.c:116: warning: implicit declaration of function `freeifaddrs'
interface.c: In function `flush_addresses':

Fixed in dhcpcd-3.0.2

Basically if we don't have glibc-2.3 present then we use ioctls, otherwise we just getifaddrs
