Unable to install Tk-804.028

Hi there,

I just tried to install Tk, but I got some errors from pngread.c:

make[2]: Entering directory `/home/viralbus/Tk-804.028/PNG/libpng'

I'm using Perl v5.10.0 built for x86_64-linux-thread-multi.

Based on a quick Google search, I'm wondering whether it's the fact I'm
using 64-bit Linux that is causing problems.  I couldn't find anything
directly related to Perl/Tk, though.

Any help would be appreciated!

Thanks,

Thomas

Upgrade libpng to a more recent version.  The troublesome MMX stuff
has been gone since libpng-1.2.20 (current version is 1.2.25).

Thanks, that worked.  I'm using Ubuntu, btw -- funny that it comes with
such as old libpng (1.2.15).

Cheers,

Thomas
