/usr/local/lib/libz.1.dylib, the file was created for i386, which is not related to architecture (x86_64)

with this problem when installing several things on my mac, I think this problem comes from updating my leopard to the snow leopard. Also this problem is also related to macports, I think.

/usr/local/lib/libz.1.dylib, file was built for i386 which is not the architecture being linked (x86_64)

Any ideas?

Update

To be more specific, this happens when you install nokogiri gem

and the log is as follows:

MacPorts: zlib i386, x86-64. :

  • . , zlib : sudo rm /opt/local/lib/libz*
  • zlib -
  • ./configure, make sudo make install
  • , ruby ​​ ( RVM)

  • Perhaps you have x86_64 compiled zlib installed in   /usr/local/opt/zlib/or, alternatively, brew install zlib this will install zlib in /usr/local/Cellar/.
  • Temporarily delete libz.*from the /usr/local/lib/backup folder.
  • Do gem install nokogiri -v '<version>' --with-zlib-dir=<zlib directory path from step 1>

Nokogiri should now be installed. Restore your libz backup again.
