for a while

the [PAM] configuration -- screwing anyone who used any non-standard [PAM] options

-By far
the best recommendation is to grab
the very excellend

. This modifies
portage slightly
, and saves any ewarn or einfo output to
a specific logdir
. You can then run <tt>enotice<
/tt> to browse them
.
+* Don't emerge lots of packages at once. And make sure you read
the output. This isn't overly useful advice.
+* Set
the <tt>PORT_LOGDIR</tt> variable in <tt>/etc/make.conf</tt>, and read over the log files generated by each <tt>emerge</tt> process. Or better yet, grab
[portlog-info
|http://tdegreni
.free.fr/
gentoo/portlog-info] to parse the output and give you the bits you want

!!! <tt>USE</tt> flags for specific packages
You can set specific <tt>USE</tt> flags for a given package in the package attribute <tt>/etc/portage/package.use</tt>. Those flags will then be applied to that package as though they were specified on the CommandLine. Eg., to build BitTorrent without [X11] support:

-* enotice - this little tool keeps track of important information and notices (einfo / ewarn) from ebuilds, and logs them away for you to inspect.
