Bugzilla Bug 212160

Previously in bug 191746 due to the changeover from app-crypt/libgssapi to
net-libs/libgssglue. the package net-fs/nfs-utils had some problems. A new
problem has come up. When building net-fs/nfs-utils 1.0.12-r1 to 1.1.0-r1 with
the kerberos flag on always comes up with this error (in more detail below):
rpc/auth_gss.h: No such file or directory
Tried on AMD64 and X86 stable
I have also tried 1.1.1 with unstable.
The error area:

it does build with 
-nonfsv4
however I want to use kerberos with nfsv3

So when the problem is when I build with -nonfsv4 and try to mount a nfsv3 (no
nfsv3 in kernel on client or server) I get the error message:
Mar  3 22:12:47 [mountd] refused mount request from spider.host.local for
/mnt/silb2/bglobal (/): not exported
So I am sure it thinks kerberos == nfsv4

could be a heimdal problem, here it builds with mit-krb5.
But i get strange errors on one box all is fine on several other boxes i get:
rpc.gssd -f
rpc.gssd: undefined symbol: gss_mech_initialize: searching for symbol
'gss_mech_initialize' in ''

with the effect that i get this when trying to use those boxes a server (as
client with the fine box the do it):
mount -t nfs4 -osec=krb5 filer:/fm1007 /mnt/cdrom/
mount.nfs4: mounting filer:/fm1007 failed, reason given by server:
  No such file or directory

ok, i build it with mit-krb5 and all is fine, one problem was a empty line and
the end of /etc/gssapi_mech.conf (the error message of rpc.gssd) (btw, why is
this file not supplied anymore?)
and the second thing was, that the new file server is an 64 Bit xen guest, so i
have to use th e-xen sources which are only available as 2.6.21 so the option
style of the /etc/exports file was not supported (the style i used is only
support since 2.6.23 (or later))

florian

kerberos only gets used when nfsv4 support is enabled.  so building nfs-utils
with USE="kerberos nonfsv4" doesnt make any sense.
