The following are from the command line because it's easier for me. You should be able to install these programs via your favorite GUI installation tool.
# aptitude install recoll
and let the automated installer program handle the dependencies and (hopefully) install the helper apps you'll want. Or install from the GUI program installer of your choice.
For Fedora Core/RHEL users, try
# yum install recoll
Or you can go to
<a href="http://www.lesbonscomptes.com/recoll/download.html">the recoll download page</a>
At the download page, distribution-specific binaries and a tarball are available. The dependencies are the Xapian database and Qt.
For idinfo MP3 ID3 tag reader:
# aptitude install libid3-3.8.3-dev libid3-3.8.3c2a libid3-dev libid3tag0 libid3tag0-dev
Some of these are probably not required, but there's no real reason not to simply install them all from the same command as shown above. Running the "for idinfo" commands is not important if you don't care to make your music searchable.
For image tag search:
# aptitude install libimage-exiftool-perl
