My mistake. The error actually is in src/snc. With the following in the
Makefile I get it to build:

snc_LIBS += seq pv ca Com

This is what was previously in the Makefile:

snc_LIBS += $(EPICS_BASE_IOC_LIBS)
snc_LIBS += pv seq

It is of course completely obvious that the libraries are listed in the
wrong order here, right? Have I mentioned before that I hate ld?

Anyway, will make a patch and a new release.

Cheers
Ben
