Dear Orsola, I'm sorry to hear you're having troubles with the install script; if we can get your installation working, I'll be sure to include any changes that are necessary in the documentation and the installation script. What I think might be going on, but I am not entirely sure of, is that the libz.so.1.2.3 library may be getting built incorrectly. In my installations on Snow Leopard, the first compiler identified by the installation script is that provided by Apple, which defaults to building with -dynamiclib, resulting in shared libraries that are built the way Apple intends them to. It looks to me like your zlib configuration is getting a different [g]cc compiler. Could you ensure that your PATH environment variable includes: /usr/bin/ *before* any other (/opt/bin, /sw/bin, /usr/local/bin) directories? This should make sure that the correct gcc is identified and used. If you could make this change, and then remove /Users/orsola2/Work/codes/yt-i386/ and re-run the script, it may correctly work. If not, please feel free to email me directly, and once we have it going I will summarize back to the list and fix the installation script.
