It does not for me. I would presume one needs NORMT3 installed first,

True. And that function is really for complex arguments, and does not
work correctly on 64-bit machines, e.g.
erf(1)
Error in erfc(z) : Error code from TOMS 680 was 1
Perhaps more helpful is to point out that erf and erfc are simple
transformations of pnorm. RSiteSearch("erf") gave several results such as

which all point you to example(pnorm) for the details. I'll add
appropriate \concept fields.
