the message that it failed for some reason and some places to find the logs of
what went wrong.

Reproducible: Always

Steps to Reproduce:
1.USE=server emerge --reinstall changed-use vnc
2.
3.

Actual Results:  
Contents of build.log.

Expected Results:  
Installation of VNC, so I can access my other Xubuntu box over the internet.

I had Openoffice.org open, file-roller, xfce4, mousepad running, as well. AMD
Athlon XP, 512 mb, ATI Radeon Mobility M1.

build.log 

This is one of the things that was generated when emerge failed.

aclocal-6966.out

Something else emerge spit out instead of installing VNC.

My environment, I'm assuming.

post your `emerge --info`

I have the same error. Here is my emerge --info.

Adds new line for each AC_SUBST argument.

I believe the important thing about Richard's information is that he has the
server USE flag set, which is documented in his environment. Applying the
attached patch in the if use server flag conditional branch fixes this problem
for me.

He also has the following in his 'emerge --info':
ACCEPT_KEYWORDS="x86 ~x86"

The problem is caused by the keyword masked version of sys-devel/autoconf-2.62.
Everything works as it should if using the stable autoconf-2.61 version.

Fixed in patchset 0.4, thanks for the patch!
