[CentOS] How to resolve an up2date package conflict? [SOLVED]

[Olaf Greve]

Hi,

Firstly: I solved the problem. For those who find it interesting to  
see where the issue resided, and how it was solved, I have posted the  
details down below.

 >really doing?

Yep.

 >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"?

Been there, done that. This results in (for "yum update" and "yum  
update gcc"):

---> Package gcc-objc.i386 0:3.4.6-3.1 set to be updated
---> Downloading header for gcc4-c++ to pack into transaction set.
gcc4-c%2B%2B-4.1.0-18.EL4 100% |=========================|  32 kB     
00:00
---> Package gcc4-c++.i386 0:4.1.0-18.EL4.3 set to be updated
--> Running transaction check
--> Processing Dependency: gcc = 3.4.5 for package: libtool
--> Finished Dependency Resolution
Error: Missing Dependency: gcc = 3.4.5 is needed by package libtool

 >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.

Yes. I agree in resorting to the last resort, so I tried that, and  
this resulted in the message: "error: "libtool" specifies multiple  
packages"

But wait!
Now there we have a really good clue as to what is going on!!!  
Multiple packages does not sound like a desirable situation!!

Sooooo, trying to use yum instead shows something highly interesting:

yum remove libtool

There ya go!
No idea how both versions could have gotten installed, but this is  
definitely way off.

I removed both packages, and afterwards a "yum update gcc" worked  
fine, then I ran "yum update" and that finished without any problems  
too. Finally, I ran "yum install libtool", and that worked smoothly  
too (it installed the "c4.4" version mentioned above).

All swell now, and tnx everybody for your help! :)

Cheerz,
