With pkg(8) installed, this might be better spelled as eg,
# pkg shlib libicuuc.so.52
which will tell you those packages that have binaries that load that
specific shlib. To find all the consumers of any shlib provided by the
icu-52.1 package:
# pkg info -qb icu-52.1 | sed -e 's/.1//' | xargs -L 1 pkg shlib -R
The sed stuff is due to the lingering legacy effects of the shlib ABI
version being required to be a single integer value, whereas nowadays
more complicated version numbering schemes seem to be all the rage.
pkg-shlib could do with growing some different matching algorithms and a
less chatty mode for use in scripting.
Cheers,
Matthew
