apt-get!?!

[langley <langley yahoo com>]

Hi folks,
  I'm a gtkmm newbie... or at least I want to be!
But I'm having a heck of time with the directions for downloading the 
binaries using either apt-get or yum... even cutting and pasting from 
http://www.gtkmm.org/download.shtml doesn't work. Has anyone else gotten 
these directions to work?

I'm on fedora 3 and I use apt-get regularly (as well as uptodate which 
uses yum).

Here's the transcript of an apt-get attempt:
[root prospero ~]# apt-get install libgtkmm2.4-dev
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package libgtkmm2.4-dev
[root prospero ~]#


Here's a transcript of the yum attempt:
[root prospero ~]# yum install gtkmm24-docs

[root prospero ~]#


And here's what I get when I try to run [jlangley prospero project2]$ 
./autogen.sh
.... <lots of configure checking...>
checking for pkg-config... /usr/bin/pkg-config
checking for gtkmm-2.0 >= 1.3.0... Package gtkmm-2.0 was not found in 
the pkg-config search path.Perhaps you should add the directory 
containing `gtkmm-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtkmm-2.0' found

configure: error: Library requirements (gtkmm-2.0 >= 1.3.0) not met; 
consider adjusting the PKG_CONFIG_PATH environment variable if your 
libraries are in a nonstandard prefix so pkg-config can find them.
[jlangley prospero project2]$

I suppose I should add that this is code generated from glade while 
selecting the c++ option of code generation.
Thanks in advance for any and all suggestions and insights!
