Here's how to rebuild source RPMs on your computer.

First, if you do not already have one, you will need to set up a workspace for building RPMs. This requires nothing more than creating a simple .rpmmacros file and an rpms/ directory under your home directory. If you are using Fedora Linux, you can accomplish this goal by installing the rpmdevtools package and then running the rpmdev-setuptree command:

$ sudo yum -y install rpmdevtools
$ rpmdev-setuptree

Otherwise, the following shell commands will do the trick:

$ echo %_topdir ~/rpm >> ~/.rpmmacros
$ mkdir ~/rpm/{BUILD,SOURCES,SRPMS,RPMS,SPECS}
$ mkdir ~/rpm/RPMS/{i{3,5,6}86,noarch,athlon}

Then you can rebuild packages from their .src.rpm files with a single command:

rpmbuild --rebuild package-name-version-release.src.rpm

When the rebuilding process is complete, your new RPM file(s) will be located in the appropriate architecture-specific subdirectories of your ~/rpms/RPMS/ directory.

Example: Rebuilding perl-Test-LectroTest

Here's how you would go about rebuilding perl-Test-LectroTest version 0.2007 from its .src.rpm file:

$ rpmbuild --rebuild perl-Test-LectroTest-0.2007-1.src.rpm

The resulting output is verbose but informative. In particular, note the "Wrote: file" lines near the end, which tell us exactly which RPM files were created for us.

When everything was said and done, one custom-built RPM file was created:

Wrote: /home/thor/rpm/RPMS/noarch/perl-Test-LectroTest-0.2007-1.noarch.rpm

We can then install this package like normal:

$ cd /home/thor/rpm/RPMS/noarch
$ sudo rpm -Uhv perl-Test-LectroTest-0.2007-1.noarch.rpm

And that's all there is to it!
