zlib doesn't provide libz.dylib

[jamie@…]

I originally tried to install without apple developer tools. I add them and then I get.

Please remember to preview and use WikiFormatting, fill in the Port field, and cc the maintainer.

And what happens when you do what the error message says, e.g.

sudo port -n upgrade --force zlib

I was able to resolve this by forcing ssl, zlib, then sql5.

Ok, great. If you ever figure out why the expected libraries weren't provided by those ports in the first place, please let me know; it's been reported a few times before and continues to baffle me.

[jamie@…]

I originally didn't have the mac dev. tools installed and the port failed due to not having make. I then installed the mac dev tools and ran into the problem. Maybe that is it.

If this was caused by not having Xcode installed when trying to install zlib, or by having a too-old version of Xcode installed, then I fixed it in r68569 by checking for a valid Xcode version.
