   This requires IPC support?

Not for the logging application --- plain 'ol Unix pipes work fine for
that.  Where NCSA 1.4 gets into real arcana is that it requires the
ability to transfer a *file descriptor* from one process to another
--- a feature which is present in most Unix variants these days, but
not all, and to which there is no single standard interface which can
be relied on to work...
