 I should note that the very guest (L1) I was trying to run virt-builder
 on, was created using virt-builder on L0. Only difference I see -- L0 is
 running F20 Kernel - 3.12.8-300.fc20.x86_64, while L1 is running the
 latest (3.14.0-0.rc0.git9.1.fc21) from current Rawhide. 
Ok, w/ L0 & L1 both at 3.12.8-300.fc20.x86_64, I still see the same
undefined --  undefined symbol: nettle_secp_256r1
I could independently confirm this by running virt-install on L1:
[. . .]
Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-install", line 31, in <module>
    import libvirt
  File "/usr/lib64/python2.7/site-packages/libvirt.py", line 28, in
<module>
    raise lib_e
ImportError: /lib64/libgnutls.so.28: undefined symbol: nettle_secp_256r1
[. . .]
I wonder, is this probably because, I'm mixing versions?
