genpkey DSA error

[leamhall@xxxxxxxxx (Leam Hall)]

More than likely it's operator error.

OS Version:
	CentOS 6, patched.

openssl version:
    	OpenSSL 1.0.1e-fips 11 Feb 2013

Works:
	openssl genpkey -algorithm RSA -out fred_ssl.key
	........++++++
	........++++++

Fails:
	openssl genpkey -algorithm DSA -out fred_ssl.key
	Error generating key
	140421332879176:error:0A07906B:dsa routines:PKEY_DSA_KEYGEN:no 
parameters set:dsa_pmeth.c:271:


Suggestions?

Thanks!
