Compile libmng without lcms support?  I'm pretty sure it's optional,
and qt-meta doesn't care what USE flags are set for libmng.  No one
uses the mng format anyway, so it isn't much of a loss.

While it isn't optimal, it's possible to get any ebuild that was ever in the
main tree from the attic if you need to fill in gaps for a new installation:

https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/?hideattic=0

Some ebuilds from this source may need to be retouched before portage
is happy with them, but if they're not too old it's usually possible to get them 
working.

There's also the option of trying the Trinity Desktop Environment, if 
ebuilds for the packages you want are available.  There's an unofficial overlay
for the most recent release at https://bitbucket.org/mgebert/gentoo-trinity
Trinity is still being actively developed, and bugs about failures to compile
against modern libs should be addressed over time.  (Sometimes over a
lot of time, granted, but no-one's perfect.)
