Okay, I think we're closing in on it. The Cepstral swift package runs fine on archlinux, where using ldd -r on the executable lists eleven libraries, all but one of which is present on Debian where the Cepstral package fails. On Debian, ldd -r on the executable says simply "not a dynamically linked executable."
The item found on Arch but missing on Debian is: /lib64/ld-linux-x86-64.so.2 (0x00007fd2b1fd1000) Any idea where to go from here? Chuck -- A bicycle can't stand alone; it's just two tired. Willoughby Ohio Temperature 57°F Conditions Mostly Cloudy The Moon is Waxing Crescent (5% of Full)
