我正在從 OpenBSD-current 運行 Tex Live 2013。 biblatex 和 biblatex-chicago 的版本似乎有點舊，這反過來又導致我的一些文件無法編譯。
我已經從 CTAN 下載了這兩個軟體包的最新版本並將它們放在我的~/texmf資料夾中。kpsewhich似乎找到了正確的版本：
% kpsewhich biblatex.sty biblatex-chicago.sty
/home/peter/texmf/tex/biblatex/latex/biblatex.sty
/home/peter/texmf/tex/biblatex-chicago/latex/biblatex-chicago.sty
編譯導入 biblatex-chicago 的文檔失敗。我相信這是因為 pdflatex 正在尋找這些軟體包的舊版本，儘管 kpsewhich 看到了正確的版本：
% pdflatex summaries.tex
This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013-OpenBSD_Ports)

我發現這個問題描述了 pdflatex 的修補版本的問題。但是，由於我使用的是 texlive 的打包版本，因此我不完全確定重建 pdftex 是正確的方法。我開始懷疑這是 OpenBSD texlive 套件中的一個錯誤，但我將其作為一個問題發佈在這裡，以防我只是愚蠢。
