That's reasonable, since I don't use Evolution.  (I use kmail for mail,
pan for news, and don't need Evolution's other features.)

You may wish to file a bug on that, altho I can't say you'll get a good
reception.  See my related bug on modular-X:

http://bugs.gentoo.org/show_bug.cgi?id=116698

If evolution has anything setuid, as was the case with xorg, it may help,
since portage's handling of that was one thing that eventually turned the
above bug toward satisfactory resolution.  I have no idea whether
evolution has anything setuid or not.

As for that ldflag, it's not major, more a personal preference.  In most
cases, what it does is force library resolution and function loading at
load time instead of waiting until the functionality is required in some
cases.  This results in a slightly longer load time, particularly shortly
after a reboot when nothing's yet in cache or loaded by other apps, and
slightly higher memory usage as well.  That's the negatives, along with
the occasional app that has problems with it. The positives are that if the
library isn't found, you know about it at load time instead of possibly
having the app crash later when it tries to load the functions, a bit more
responsiveness after load the first time those functions are used (when
the system would otherwise be loading the library and linking in the
functions on demand), and a bit better security.

All in all, as I said, it's a personal preference.  I don't specifically
recommend it as an optimization, and in fact, for those with less than a
gig of memory (as well as those who don't want the occasional hassle with
an app allergic to the setting), I'd tend to recommend NOT using it.

As for LDFLAGS in general, I've mentioned previously that I'm looking for
more documentation on them.  There's some others I've seen in bug
reports or mentioned in passing that look interesting, but I simply don't
/begin/ to know enough about them to even /consider/ using them at this
point. Until that changes, I leave well enough alone.
