I doubt that you got it from Ubuntu or Debian. I have been maintaining
packages for Debian since 1995, and covered R related packages including R
itself since the late 1990s. I'd think I'd know.

A formal search for the library via packages.debian.org brings up nothing:
http://packages.debian.org/search?searchon=contents&keywords=%2Fusr%2Flib%2FR%2Fsite-library%2FRInside%2Flib%2FlibRInside.a&mode=path&suite=unstable&arch=any
Dito via apt-cache search on my Ubuntu (12.10) machine.  You may have gotten
it from some non-official source, maybe even Michael's PPA --- but you have
to understand that that alone makes it NON-STANDARD and I have been trying to
explain to you over what must by now be 5 emails that you are better off
minimizing variability. 

It works for me. I have no prebuilt RInside.  Hint: Maybe remove yours.

If in doubt install RInside from source.

It doesn't matter. We build the .a because that is what R does, and on some
platforms it is needed. No use to suppress.

The one that is used is the .so. Just trust me on that.

Because I work from (SVN) source, you don't. Maybe you should untar the
source tar.gz somewhere and work from it.

In the grand scheme does not matter.

Make sure you work in a directory you have write access. If you naively did a 

     cd /usr/local/lib/R/site-library/RInside/examples/qt

then you usually DO NOT. Copy to /tmp, or your $HOME, or somewhere.

Well, doh.

I told you several times now that my code is UNTESTED AGAINST Qt 5
and that you should use libqt4 on your Ubuntu system -- unless you know what
you are doing.

Which, seemingly, you don't. 

I have other stuff to do (as eg re-building 100 or so r-cran-* packages for
the upcoming R 3.0.0 release) so I should really stop here.

Wrong. 

I happen to think that I know what I am doing with a piece of software I
co-designed and wrote. It even works for me, and I showed you how to do it.

You insist on doing it your way -- which is perfectly fine. 

But please understand that you then cannot call repeatedly for help.

I already have.  Look at the last email.

PS  Why do you keep another source copy in the install directory?
