I am using Arch Linux, but I installed TeX Live from the network, so that I can use tlmgr to install a minimal set of packages that I can add to as needed.

Here is a .tex file:

\documentclass{minimal}
\usepackage{fontspec}
\begin{document}
Forsan et haec olim meminisse iuvabit.
\end{document}

Trying to run XeLaTeX on it gets me:

! LaTeX Error: File `ifpdf.sty' not found.

If I run:

tlmgr install ifpdf

I get:

package ifpdf not present in package repository.

I am uncertain how to proceed, and have several related questions:

  1. Does tlmgr simply fail to install dependencies? I installed fontspec with no problem. If it requires ifpdf why was this not installed with fontspec?

  2. Since ifpdf seems to be a legitimate package, why is it not installing?

  3. Is there some better way I could investigate this problem on my own?

Welcome to TeX.SX! You can have a look at our starter guide to familiarize yourself further with our format. –  Martin Schröder Dec 14 '13 at 22:55
    
In general TeXLive does not track package dependencies: The recommendation is to install a scheme (or everything; hard disc space is cheap); but this one has been added. –  Martin Schröder Dec 14 '13 at 23:17

to find the TeXLive package where a style file is located run

voss@shania:~> tlmgr search ifpdf
 iftex - Am I running under pdfTeX, XeTeX or LuaTeX?
 oberdiek - A bundle of packages submitted by Heiko Oberdiek.

Install the oberdiek bundle to get ifpdf

Use \listfiles as first line in your document. Then you'll get a file list at the end of the log file:

Installing oberdiek does solve the immediate problem involving ifpdf.sty. However, tlmgr search ifpdf returned nothing before I installed oberdiek. Afterwards it returned exactly the "oberdiek" line above. So it seems the tlmgr search option only works on installed packages. Also, I guess it is necessary to just search on ctan.org and try to figure out what package is really needed. As for \listfiles it seems not to work at all yet, and XeLatex is now giving me another error about something missing. But the given problem is solved. –  Diomedes Dec 14 '13 at 9:29
