Bugzilla Bug 110034

The ebuild chmod -R 644's the dir /usr/share/doc/qwtplot3d-0.2.6/examples/, 
but doesn't set the execute bits on the dir's. The follwoing fixed the 
problem: 
 
cd /usr/share/doc/qwtplot3d-0.2.6/examples/ 
chmod 755 . simpleplot/ mesh2/ enrichments/ axes/ autoswitch/ axes/src/ 
enrichments/src/ mesh2/src/ 
   

Reproducible: Always
Steps to Reproduce:
1. USE="docs" emerge qwtplot3d 
 
 
Actual Results:  
$ cd /usr/share/doc/qwtplot3d-0.2.6/examples/ 
bash: cd: /usr/share/doc/qwtplot3d-0.2.6/examples/: Permission denied 
$ ls -ld /usr/share/doc/qwtplot3d-0.2.6/examples/ 
drw-r--r--  7 root root 1256 Oct 21  
14:49 /usr/share/doc/qwtplot3d-0.2.6/examples/ 

Expected Results:  
directory should be user readable

And...

- the license is wrong. It's ZLIB, not as-is. There are many licenses which have
an "as is" sentence, but that doesn't mean that it's the classic as-is license. 

- the examples should be installed using the exapmles use flag.

- with use foo && ( blah blah ) you unnecessarily open a subshell. if ... then
is the better choice.

Fixed I think - let me know if there are any further issues with it. Added it 
as a dep to qtiplot and didn't pay enough attention to some of the finer 
details obviously, sorry. 

I'm using qwtplot3d-0.2.6-r2 and just found that two dirs still have 644 mask
instead of 755 although there have been listed already.

This are:

/usr/share/doc/qwtplot3d-0.2.6-r2/examples/mesh2/src
/usr/share/doc/qwtplot3d-0.2.6-r2/examples/enrichments/src
