Many modern Linux distributions that use a package system have the
ability to ensure necessary dev libraries and other required tools for
building a package are installed and will install them if there not. 

For example, under Debian based systems, you have apt-get --build-dep
<package> which will install all the necessary build dependencies for a
package. This can be very useful when you want to build a later version
from sources as it takes away some of the pain of ensuring all necessary
packages are installed. 

So, when I wanted to build emacs 24 from sources, the first thing I did
was run 

apt-get --build-dep emacs23

which ensured all the necessary packages to build emacs 23 were
installed. Then all I had to do was manually add any new libraries used
by emacs 24 (in this case, there were none). 

I believe (from memory) rpm has a similar facility. Recommend you look
into it as it will help ensure your system has the necessary libs for
building emacs - may make life easier. 

If you still have problems, check the config.log file. It will tell you
what was not available and what you may still need to install.
