[GnomeMeeting-list] Dependencies errors - what can a newbie do

[Eric Lee <ericlee labourstart org>]

I'm running Red Hat 7.3, and I've downloaded all 3 Red Hat packages --

gnomemeeting-0.96.1-1.i386.rpm
openh323-1.11.2-3.i386.rpm
pwlib-1.4.7-3.i386.rpm

-- but when I do rpm -i on either of the latter two, I get the following
messages --

error: failed dependencies:
	libc.so.6(GLIBC_2.3) is needed by pwlib-1.4.7-3
	libstdc++.so.5 is needed by pwlib-1.4.7-3
	libstdc++.so.5(GLIBCPP_3.2) is needed by pwlib-1.4.7-3

When I try to run rpm -i on the openh323 file, it tells me that pwlib is
needed, as are the other files.

What do I need to do now?  

Thanks.

Eric
