[DGD] Driver error message patch

[Keith Dunwoody]

May I suggest the following patch for the driver?  On
linux systems, it will return more accurate
information if this call fails.  Originally, this call
would print "gethostbyname: No such file or
directory", which I found misleading.  After the
patch, it will print the hostname, followed by ": Host
not found" (or something like that).

P.S.  According to the man page herror() is obselete,
but I couln't find any equivilent.
