Hi,

the TikZ positioning library is part of recent PGF releases.
Unfortunately, Fedora provides by default TeX Live 2007 with an
outdated version of PGF.
You could take the latest version of PGF on the CTAN
(http://www.ctan.org/tex-archive/graphics/pgf) and install it in
~/texmf... Or simply upgrade to TeX Live 2011 thanks to the Novy's
dedicated repository:
   http://fedoraproject.org/wiki/Features/TeXLive
(be careful, the page refers to TeX Live 2012 which is still in
development; the yum repository for TL 2011 can be set using this RPM:
http://jnovy.fedorapeople.org/texlive/2011/packages.fc15/texlive-release.noarch.rpm).
