[gentoo-user] equery shows lyx didn't depend on qt, and emerge shows the opposite

[Zhang Weiwu]

Hello.

I wishes to emerge lyx and surprisingly found it depends on qt:

root@esmeralda:/home/zhangweiwu# emerge -pv lyx

These are the packages that would be merged, in order:

I thought it must not be true, because I used lyx on Ubuntu and it
doesn't look like a qt application at all. Then I run equery depgraph to
see which package required qt. again a surprise, according to equery,
lyx did not depend on qt, nor indirectly.

I attached output of 'equery depgraph =lyx-1.5.4' to this message. Do a
grep and 'qt'  is not found in the output.

So my question is:

   1. Is it true lyx really depends on qt? How do I find out?
   2. If lyx doesn't have to depend on qt, how can I install lyx and
      avoid qt being emerged?

Thanks in advance!
