I am running on Mac OS X 10.5.8, and I cannot execute the julian command, saying that it "cannot execute binary file."

I un-tar'ed julius-3.5.2-multipath-linuxbin in where my HTK is installed, and I have added paths for HTK and julius into the $PATH environment variable.  I have checked the permissions for all the files in the julius-3.5.2-multipath-linuxbin/bin directory and they all are "-rwxr-xr-x" so they all should be executable. But I can not execute any of the commands, except for the perl scripts (gram2sapixml.pl, mkdfa.pl, yomi2voca.pl)

Please help!

Thanks,
