I think the excluded list could be obtained by lib*.[0-9.]*.dylib (assuming the dot isn't a wildcard here), is there a better way to get at the list I want than to do 2 globs and then a list exclusion operation?

with tcl 8.6, one can do the following

    set excludePattern {lib*.[0-9]*.dylib}
    set files [glob -tails -dir /opt/local/lib *.dylib]
    set excludedFiles [lmap f $files {if {[regexp $excludePattern $f]} continue; set f}]

The exclude pattern can contains certainly "|" for alternate exclude patterns, etc.
all the best
