Bind lockups -> upgrade attempt

[Frazier Scott]

Hi.  Please let me know if I am posting to the wrong list.

I have had numerous intermittent and (so far) non-reproducible issues with 
named (Bind 9.1.0) locking up and hogging the cpu.  My issues so far seem 
to be similar to issues I have seen documented on this mailing list.  Based 
on what I have read, my best course of action seems to be to upgrade to 
Bind 9.1.1.  Unfortunately, when I run make it chokes compiling dig with 
the error:

cc -pthread -std -g -o dig dig.o 
dighost.o  ../../lib/dns/libdns.a   ../../lib/isc/libisc.a -lpthread
ld:
Unresolved:
__h_errno
make[2]: *** [dig] Error 1

I am running Digital Unix V4.0G on a DEC Alpha 2100.  I had originally 
upgraded to Bind 9.1.0 from Bind 8.2.3.  The upgrade went fine.  Since then 
I have done the following:

Install Apache 1.3.19
Install Samba 2.07
Install jed B0.99.12
Install GNU m4 1.4
Install vim 5.7
Install groff 1.16.1
Install tcp_wrappers 7.6
Install qpopper 3.1.2
Install most of the latest comprehensive patch from Compaq for DU v4.0G - 
patch numbers 19, 24, 26, 42, 58, 63, 76, 116, 149, 164, 167, 172, 178, 
186, 2, 3, 101, 103, 132, 180, 184, 37, 40, 48, 50, 105, 114, 147, 169, 
174, 59, 77, 188, 60, 61, 137, 126, 20, 43, 53, 56, 80, 107, 145, 161, 176, 
99, 31, 46, 93, 140, 97, 28, 47, 70, 87, 122, 151, 159, 182, 95, 9, 84, 
190, 11, 12, 85, 118, 120, 128, 153, 155 (listed in the order they appeared 
in the patch utility)
Install procmail 3.15.1
Build libmilter from sendmail 8.11.3
Install sendmail 8.11.3
Install Sendmail Restricted Shell
Install pine, pico, and imapd
Install sendmail's makemap
Install sendmail's mailstats
Install sendmail's praliases
Install sendmail's vacation
Install listproc

As far as I know, none of these things should affect any attempt to compile 
Bind.  Just the same, not only can I not compile Bind 9.1.1, but also 
attempting to re-compile Bind 9.1.0 fails with the same error.

Can anyone help me out?

Thanks,

Frazier.
