For example, I can't install package qcad because of error: "can't find qdict.h".
How can I find the package which provides the file qdict.h so I can install the package qcad?

    @Joe, I illustrate: I want to install qcad, but it doesn't compile because can't find file qdict.h. I want to know which package contains that file. I've tried to google, but found nothing.

You may use the e-file command from the pfl package (emerge -av app-portage/pfl) to search by package contents.

e-file YOURFILE

Alternatively, you may use an online database.

Regarding the qcad package specifically, you probably need the Qt4 package. IIRC, use emerge -av x11-libs/qt-gui (If that doesn't work out, try searching for QT packages. Use this query: emerge -s qt.)

    To be more precise, pfl provides the command e-file Nov 5, 2013 at 11:04

    FYI, the e-file command simply queries the very same online database linked in the answer. It's called the Portage File List.
