PEAR/PECL MAMP 2.x Error : Notice: unserialize()

When i run my pecl/pear from MAMP bin folder , i got error message : 
Notice: unserialize(): Error at offset 276 of 1133 bytes in Config.php on line 1050
ERROR: The default config file is not a valid config file or is corrupted.

to fix :

• Remove the pear.conf in MAMP folder OR
• Find pear.conf, edit and change the "php_dir";s:44 into "php_dir";s:43

Now pecl/pear can run without error.
