How about making it less technical? Just say that you'll need to rebuild less packages on average after a library upgrade than before. > To gain the benefits of the change you should doublecheck your > value of LDFLAGS in make.conf because the variable does not fold and > your make.conf value is final.

How about just make sure your LDFLAGS in /etc/make.conf contains "-Wl,--as-needed" or is unset? > Overriding the in-profiles value is quite simple as described by > previous paragraph. Just put simply LDFLAGS="-Wl,01" in make.conf. Instead of saying "overriding", I'd say something more similar to "disabling --as-needed" and add that it is not recommended. > [1] http://www.gentoo.org/proj/en/qa/asneeded.xml Paweł P.S.
