I'm searching for a glob that can expand to directories and symlinks to
directories (or optionally the linked directories). I'm doubtful this is
possible as a simple glob.

Example of zsh globbing for directories, but which fails on symlinks to
directories

/usr/local/*/{bin,sbin}(#q/)

D'oh

/usr/local/*/{bin,sbin}/(#q/)

The trailing slash was troublesome, but I was able to strip it with
parameter substitution elsewhere, so presumably I succeeded without creating
any additional processes.

zsh% echo *(-/)

The (/) qualifier matches directories only, but the (-) makes it follow
symlinks.

You might want to use (bin|sbin) to do the whole thing as a single glob
instead of {bin,sbin} which expands the braced group before globbing, then
does 2 separate globs.

Off the trail a little bit, but is find an option for you ?
Some thing like , type d , then use some stars in the name parm ? just
a thought,

find /usr/local -type d -name "*bin*"

Unfortunately, that doesn't find symlinks to directories

find -L /usr/local -type d -name "*bin*"

would, but would also traverse symlinks when descending the
directories. There's no easy way to have one an not the other
without relying on an external command.

Though in the case above where we don't want to descend into
subdirectories, it would work:

find -L . ! -name . -prune -type d -print

But zsh's

print -rl -- *(D-/)

is simpler and gives you a sorted list of files.
(D is to include dot-dirs which find includes, add ! -name '.*'
to find to exclude dot-files).
