Apple introduced a compressed linkedit loader section in Mach-O binary headers in 10.6; that error is the OS X 10.5 loader not understanding the header fields. You can verify this is the case if you have the Xcode development package installed. On a 10.5.8 machine, you'll get output like this: $ otool -l denzo_3d | grep -A10 "Load command 4" Load command 4 cmd ?(0x00000022) Unknown load command cmdsize 48 00000000 00000000 00234000 00000088 00000000 00000000 00234088 000006f8 00234780 00004828 Load command 5 cmd LC_SYMTAB cmdsize 24 symoff 2330536 nsyms 6088 stroff 2429640 And on a 10.6 machine it will look like this: $ otool -l denzo_3d | grep -A10 "Load command 4" Load command 4 cmd LC_DYLD_INFO cmdsize 48 rebase_off 0 rebase_size 0 bind_off 2310144 bind_size 136 weak_bind_off 0 weak_bind_size 0 lazy_bind_off 2310280 lazy_bind_size 1784 I have filed this exact bug report with HKL Software in the past. If you wait long enough, they will usually compile a version that runs on 10.5 machines. The support email for HKL Software is supp...@hkl-xray.com. No one here can help you. Have you tried iMosflm? -ben -- | Ben Eisenbraun | SBGrid Consortium | http://sbgrid.org | | Harvard Medical School | http://hms.harvard.edu |
