Hi, While I had no problem following Matt's instructions to get Ifeffit working on my desktop after upgrading to 10.4, I'm still stuggling to install ifeffit on the new laptop. I've tried different combinations of the binary installer and manual compilations of Tcl/TK and horae, but I run into this error: %JoelG4:/Applications/Ifeffit/bin joelb$ ./hephaestus %dyld: lazy symbol binding failed: Symbol not found: _s_copy % Referenced from: /Library/Perl/5.8.6/darwin-thread-multi-2level/auto/Ifeffit/Ifeffit.bundle % Expected in: dynamic lookup % %dyld: Symbol not found: _s_copy % Referenced from: /Library/Perl/5.8.6/darwin-thread-multi-2level/auto/Ifeffit/Ifeffit.bundle % Expected in: dynamic lookup % %Trace/BPT trap Only thing I can think of at this stage is reinstalling the OS! Thanks! JOEL
