Hi,
My existing project is using IO module, project works fine on RedHat 8
(2.4.28). Where same project on my Ubuntu (linux 2.6.28) gives me error
undefined symbol: PL_curpad.

Originally project was running fine on RHEL5 U8 Linux kernal 2.4.20.
The main difference I see here is GNU C library version. The current
version of libc is 2.9.

The PL_curpad is undefined symbol in case of UBUNTU whereas it is not
defined in RHEL.

I have compiled IO on my ubuntu without any problem, I have tried both
standard and manual installation.
The perl version/distribution I'm using is 5.8.9 (ubuntu) and 5.8.8 (on
RedHat). I cannot install 5.10 as my whole project is supporting only 5.8.8.
