Notice: Type perl Makefile.PL -h for command-line option summary.

Configuring for libgd version 2.0.35.
Checking for stray libgd header files...none found.

Included Features:          GD_XPM GD_JPEG GD_FONTCONFIG GD_FREETYPE GD_PNG GD_GIF GD_GIFANIM GD_OPENPOLYGON GD_UNCLOSEDPOLY GD_ANIMGIF GD_FTCIRCLE VERSION_33
GD library used from:       /usr
Have /usr/perl5/5.12/lib/Sun/Solaris/PerlGcc
Want /usr/perl5/5.12/lib/i86pc-solaris-64int
Your perl and your Config.pm seem to have different ideas about the
architecture they are running on.
Perl thinks: [PerlGcc]
Config says: [i86pc-solaris-64int]
This may or may not cause problems. Please check your installation of perl
if you have problems building this extension.
Note (probably harmless): No library found for -liconv
