The .paths feature doesn't work with ast-open-2014-09-29, although
it appears that it hasn't been working at least since ksh-20120612. I
can't get it to work until I go back to ksh-20081104. The following
illustrates what I mean:
$ IFS=:
$ set -- $PATH
$ IFS=,
$ ls {"$*"}/.paths 2>&-
/opt/ast/bin/.paths
$ IFS=''
$ ls -ld /opt /opt/ast /opt/ast/bin /opt/ast/bin/.paths

Usage: ratz [ options ]
OPTIONS
-c, --cat|uncompress
Uncompress the standard input and copy it to the
standard output.
-l, --local Reject files that traverse outside the current
directory.
-m, --meter Display a one line text meter showing archive read
progress.
-n, --convert In ebcdic environments convert text archive
members from ascii to the native ebcdic. On by
default; -n means --noconvert.
-t, --list List each file path on the standard output but do
not extract.
-v, --verbose List each file path on the standard output as it
is extracted.
-V Print the program version and exit.
$ exit
I have been unknowingly skirting this issue by explicitly exporting
DYLD_LIBRARY_PATH=/opt/ast/lib in my .profile (I unset DYLD_LIBRARY_PATH
before running the example above). For those in the community who are
not familiar with Mac OS X, DYLD_LIBRARY_PATH is a Mac-OS-X-specific
setting. Most other Unix dialects use simply LIBRARY_PATH.
