I don't think anything in Cactus itself would do this.

Probably some external library being linked into Cactus has a link to 
libhdf5.so.1, which existed at the time when (or on the system where)
it was linked.

There are only a few external libraries linked in by Cactus.  You should
be able to track this down by looking at the command line that does
linking:  remove your Cactus executable from the exe directory, and
re-make the config, with SILENT=no.

Cheers!
