Try to upgrade syslog-ng to newer version 1.6 from 1.4

then it asks for other package.

#:rpm -iv syslog-ng-1.6.11-21.i586.rpm
error: Failed dependencies:
klogd is needed by syslog-ng-1.6.11-21
libc.so.6(GLIBC_2.4) is needed by syslog-ng-1.6.11-21

when I try to install klogd, it give me another error.

# rpm -iv klogd-1.4.1-584.i586.rpm
