最近写的一个东东要用python25和python-ldap，但是使用的那台主机是python23、ldap2.2.x和python-ldap2.0.1。安装了一个python25，python-ldap是2.3.8，编译失败，openldap2.2太老了，python-ldap2.3.8不向下兼容了。

那我就用python-ldap2.0.x，这个版本已经不提供下载了，从sf.net的cvs上拉了一份2.0.11的版本，这次倒是编过去了。用的时候出问题了

*** glibc detected *** free(): invalid pointer: 0xb7f60728 ***
Aborted

查来查去有三个文章有说这种情况

• problem using python-ldap under fcgi
• python-cdb double free
• 解决之道：python-cdb 0.32 (-5.2ubuntu2) with Python 2.5 causes double-free corruption crash on dealloc

sed -i.orig 's/PyMem_DEL/PyObject_Del/g' Modules/LDAPObject.c 
sed -i.orig 's/PyMem_DEL/PyObject_Del/g' Modules/ldapcontrol.c 

然后再build，install就OK了

今天在公司做了一个简单的python介绍。Presentation放在了SlideShare，几个用例则放在了github

在python中与svn进行通信交流是少不了pysvn这个C扩展的，但无论是在FreeBSD还是Mac OS X下安装这个家伙都是对自己RP的一种考验。

其实错误主要来自编译的时候会有一个dylib找不到

powerpc-apple-darwin9-g++-4.0.1: /opt/local/libpython2.5.dylib: No such file or directory
make: *** [pysvn/_pysvn_2_5.so] Error 1

那么就改造一下Makefile吧，patch如下
