libobjc is only installed as a dependency if you're installing the
gcc-objc package, not just plain gcc. Are you telling us what you're
really doing?  If libtool requires gcc and libtool is already on your
system, then you must also already have gcc.  So why aren't you using
"yum update gcc" rather than "yum install gcc"?

Have you tried simply "yum upgrade" (with no specific packages listed)
to bring the entire system up to date?  If not, why not?

As a last resort I'd suggest that you try removing libtool entirely
(rpm -e libtool), then installing whatever gcc packages you are after,
and then try re-installing libtool.

It does seem a little odd that libtool has a specific "gcc = 3.4.5"
dependency ... however, on my CentOS 4.4 box it reports "gcc = 3.4.3"
and I didn't have any trouble updating gcc:

%  rpm -q libtool
libtool-1.5.6-4.EL4.1.c4.4
% rpm -qR libtool
/bin/sh
/bin/sh
/bin/sh
/sbin/install-info
autoconf
automake
gcc = 3.4.3
libtool-libs = 1.5.6-4.EL4.1.c4.4
m4
mktemp
perl
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
% rpm -q gcc
gcc-3.4.6-3.1
