cmake fails because of XML linking error (expat issue?)

[jpsdotcom@…]

Am using OS X Yosemite & XCode 6.1

from main.log after "port install cmake" fails:

I didn't realize how bad the formatting would be, so here is the snip from main.log, again:

Hi,

I'm running into the same problem.

What I did :

• Uninstalled "ports" by following the uninstall guide : ​https://guide.macports.org/#installing.macports.uninstalling
• Installed MacPorts-2.3.2 from sources
• Ran "sudo port -v self update"
• Ran "sudo port install cmake"

"expat" dependency seems to be the culprit : it doesn't contain a x86_64 slice as expected. Expat version is 2.0.0.

I'm running Yosemite with Xcode6.1 (latest command line tools installed) on a 3,4 GHz Intel Core i7.

Thx

Arnaud F.

Attach the config/build log. It appears to be grabbing the wrong expat.

Please use WikiFormatting when posting in trac, and fill in the port field when reporting bugs against ports. Please also Cc the maintainer, if any.

As per the wiki:FAQ#buildfails, please also try sudo port clean cmake followed by sudo port -t install cmake (which will hide your bogus copy of expat in /Library/Frameworks from cmake's build system at the cost of performance).
