我刚刚使用 tlmgr 安装了 newtx 包。（如果这很重要的话，我仍然在使用 TexLive 2011。）安装没有导致任何错误消息 - 但是当我尝试使用该包时，我确实收到了奇怪的错误消息。
这是一个最小（非）工作示例：
\documentclass{minimal}
\usepackage[libertine]{newtxmath}
\begin{document}
Foo bar $x \phi$ baz.
\end{document}
结果是这样的：
This is pdfTeX, Version 3.1415926-2.3-1.40.12 (TeX Live 2011)

有什么想法吗？
编辑：升级到 TexLive 2012 并安装当前版本的 newtx 后，我收到一系列错误消息，开头如下：
