Description:
------------
I tried to install PEAR under php v 4.2.1, but the command in the documentation: 

# lynx -source http://go-pear.org/ | php

Fails with the following:

PHP Fatal error:  Call to undefined function:  set_include_path() in - on line 594


Test script:
---------------
Sure enough, 
http://www.php.net/set_include_path

tells me that this wonderful system call is >= 4.3.0 only!

I made the a simple change to a local copy of go-pear.php and it chugged along merrily.

This following 4-line diff should fix it for everyone:

594c594
< set_include_path($ptmp);
---
> ini_set('include_path', $ptmp);

Gavin.


Expected result:
----------------
Should install on PHP v4.2.0+

Actual result:
--------------
only installs on PHP v4.3.0+

go-pear.php dies with:

PHP Fatal error:  Call to undefined function:  set_include_path() in - on line 594
