I get this very mysterious message I hope it is not a linker issue, because I am using a recent ld64 suggested by Ken needed for other packages!

leopard's libc doesn't have that function, but it can be replaced usually by adding the legacysupport PortGroup.

[kencu (Ken)]

I added legacysupport on my own copy, and it does fix the gd2 port.

On PPC Tiger, Mac OS X 10.4.11, the same error happens and the same solution works.

[rmottola (Riccardo)]

Works for me too

PortGroup                   legacysupport 1.0

Not knowing what version number to add I put 1.0, but it worked

[ballapete (Peter "Pete" Dyballa)]

On PPC Leopard, Mac OS X 10.5.8, same error and same cure.

[ballapete (Peter "Pete" Dyballa)]

In case you'll want to find the version number in the future again, this command from the command line in bash or zsh will give you a few examples:

find $(dirname $(dirname $(dirname $(port file gd2)))) -type f -name Portfile | xargs grep -i 'legacysupport '

(In case you'll find a shorter Port name than gd2 substitute that one for gd2 – and you'll save at least one character to type (or copy)! And maybe half a CPU cycle…)
