There doesn't seem to be a consensus upstream about the nature of the
problem, and whether this is the proper fix, which is why it was not
included in recent releases.  I will look into this.

This is not a typo: libalapack.so is the math/atlas lapack library
that should be used in lieu of the bundled libRlapack.so when
WITH_ATLAS is selected.  The patch instructs R to use a mixture of
libraries from math/lapack and math/atlas, and this is wrong.  If the
submitter wants to use alternative blas and lapack libraries (other
than math/atlas) instead of the bundled blas and lapack, he can set
WITHOUT_ATLAS, BLAS, and LAPACK to appropriate values in his build
environment or an included Makefile.  If there is a problem with R
when the non-default option WITH_ATLAS is selected, I suspect it is
due to some problems with math/atlas that I have yet to correct after
recently succeeding Maho as maintainer of the atlas ports, but this
needs investigation.  I will also look into this.

I looked at the first issue, and, as the upstream developers said when
they refused to accept the patch, this code is not expected to work
with the cairo device, which does not generate or handle events:

"the problem was that the code did not check that the device was capable of
generating events, so it would wait forever for something that
wouldn't happen..."

which is why the check that bars the use of the cairo device with this
code was introduced.  So it would not be a good idea to introduce this
patch (which the submitter acknowledged was incomplete, anyway).  You
can however switch devices, and then use example(getGraphicsEvent...

In the new version of R which will be coming out near the end of the
month, this area has been substantially reworked, with many fixes and
extensions for the cairo and other graphics devices.

With regard to the second issue, the failure in your example was, as I
expected, due to the long-standing problem with the construction of
the atlas shared libraries, which lack some tags to assist the loader.
I have prepared an atlas update which fixes this and some other
problems, and I am waiting for feedback from some testers.  I will
probably be able to commit that update soon.

From-To: open->closed

The ATLAS problem should now be fixed after the update of math/atlas.
