The sure fire way would be to do:
[declare -lib share-mem -path ..]
.hc

Or if you find the patch on the net, the [declare -lib] will tell you that you need to get the 'share-mem' library in order for the patch to work. Otherwise, you have to guess where [shmem] came from.

An alternative is to use [declare -lib share-mem], then it'll work wherever as long as share-mem is installed. The downside there is that the library needs to be in the standard install location or the path in order for that to work. For development, I often put a symlink in ~/pd-externals to the folder in SVN, then it works everywhere.
