Perlbrew -安装术语：：ReadLine：：Gnu on OS X

Question

尝试在OS X上安装Term::ReadLine::Gnu。make test返回错误，如：

t/00checkver.t .. 1/3 panic: free from wrong pool, 62696c2f62696c!=7f8ed2801200 during global destruction.

搜索后，找到一个建议，用-DPERL_USE_SAFE_PUTENV编译perl。于是，尝试了下一个：

perlbrew install perl-5.16.3 --thread --multi --debug -DPERL_USE_SAFE_PUTENV

需要线程，因为Padre需要线程。不幸的是，重新编译无助于获得相同的错误。接下来，我发现了这个What is the cause for “panic: free from wrong pool during global destruction.” in Term::ReadLine::Gnu?问题，accepted answer建议使用：-Accflags="-DPERL_USE_SAFE_PUTENV"。

问题如下：

• 主要是如何使用perlbrew获得一个工作术语：：ReadLine：：Gnu
• 如何用perlbrew编译/安装/切换perl以使perl为Padre工作，需要的是Term::ReadLine::Gnu。

只是好奇：

• 如果perl需要一些"SAFE_PUTENV“来编译一些CPAN模块，为什么它不是默认的呢？为什么有人想要一个perl，在那里不可能编译一些CPAN模块？
• 有人在OS上工作Padre & perlbrew吗？

如果有人需要：

正如问题中所链接的，答案已经在this answer中了。运行：

 perlbrew install perl-5.16.3 --thread --multi --64all --debug --clang -Accflags="-DPERL_USE_SAFE_PUTENV"

使用这个perl可以成功地安装：

$ cpanm Term::ReadLine::Gnu

在达辛姆的回答中，没有什么地方比-Accflags更适合perlbrew了。确实需要阅读perlbrew help，其中有明确的说明：

-D,-U,-A       Switches passed to perl Configure script.

无论如何，仍然不明白为什么OS是-Accflags="-DPERL_USE_SAFE_PUTENV"而不是默认的，而是经验教训：

对于OS，当使用perlbrew构建perl时，普通用户应该使用。

perlbrew -Accflags="-DPERL_USE_SAFE_PUTENV"`

来获得一个有效的perl。
