What does

	locate ctable

(typed in a terminal window) give you?  I get (a whole load of stuff) and
      .
      .
      .
/usr/local/texlive/2008/texmf-dist/doc/latex/easy/doc.dvi/doctable.dvi
/usr/local/texlive/2008/texmf-dist/source/latex/ctable
/usr/local/texlive/2008/texmf-dist/source/latex/ctable/ctable.dtx
/usr/local/texlive/2008/texmf-dist/source/latex/ctable/ctable.ins
      .
      .
      .

Also does

	texdoc ctable

give any results?

If either of these commands gives a result, then you *have* ctable.  The reason
that pdflatex isn't finding it may relate to your tex search path (controlled by
the environment variable TEXINPUTS) --- but normally you should not need to set this.
