Bugzilla Bug 18291

Hello 

I've tried to install djbdns-1.05-r7 with MAKEOPTS="-j4". 
And the compilation crashes everytime. 
Here is the output 
<------------->
./compile log.c 
./compile cache.c 
./choose c trydrent direntry.h1 direntry.h2 > direntry.h 
In file included from cache.c:7: 
dns.h:63: parse error before "iopause_fd" 
dns.h:64: parse error before '*' token 
make: *** [cache.o] Error 1 
make: *** Waiting for unfinished jobs.... 

!!! ERROR: net-dns/djbdns-1.05-r7 failed. 
!!! Function src_compile, Line 39, Exitcode 2 
!!! emake failed
<------------->

I have disabled the MAKEOPTS in /etc/make.conf and all is ok right now, so the 
ebuild process should avoid the use of jobserv for djbdns. 

Please not a I have a true SMP machine. 
2 P4 XEON 2.4Ghz + 1Mb L2 cache.

Reproducible: Always
Steps to Reproduce:
1. Set MAKEOPTS=-j4
2. Use a TRUE MultiProcessors Plateform
3. Emerge the PAckage

Actual Results:  
The compliation fails

Expected Results:  
Unset MAKEOPTS

try -j1 and/or remove ccache

Same problem here, using -J1 allows installation to complete. If possible, the
ebuild should force -J1

The ebuild needs to force -j1 for MAKEOPTS, removing ccache doesn't help at
all.  Of course retrying multiple times will eventually get it to build as
well, but its definately not thread safe, even on a singel CPU system.  I
wasted tons of time trying to figure out how to get this to build!

Add djbdns ebuilds have been updated with MAKEOPTS="-j1"
