Hello!
pylirc cannot be found during import in python3 scripts. But for python2 it works.
I use pip3 to install pylirc because my Linux distribution has no package pylirc for python3. But it has for python2.
Is that a bug somewhere in python3? Do you think there is a workaround?

As you can see from strace python does not try finding pylirc in its paths. And it is strange (or it is not?). Somehow python is finding < string > instead of something pylirc.
What the magic happens here? :-)

It seems pylirc c module does not compatible with python3. Because pylirc does not call PyModule_Create() as describe here https://docs.python.org/3/howto/cporting.html.

For some odd reason, the latest version of Microsoft R Open is failing to compile various packages, because of something (Rcpp I think) that spawns multiple R sessions, and the repeated calls to clear the terminal window are introducing line breaks in the middle of the compiler commands. See below. There doesn't seem to be a reliable way to completely suppress the verbose startup message, which appears to be causing this error.
Note the same happens with /opt/microsoft/ropen/4.0.2/lib64/R/bin/R CMD INSTALL as well as /opt/microsoft/ropen/4.0.2/lib64/R/bin/Rscript
Ideas? Suggestions?

Probably you need something like
!apt-get install libreadline-dev
before attempting to run the install.sh script.
I am trying to build a mapnik 2.2.0 RPM file on my RHEL/CENTOS 7 machine.
so I took the RPM SRC file from Fedora 22 which is mapnik-2.2.0-11.fc21.src.rpm ( I have the same result with mapnik-2.2.0-5.fc20.src.rpm )
when I am running the rpmbuild I receive the following error message:

Mapnik normally comes with a heavily patched version of the AGG library right there in its source tree. The Fedora build however disables that in favour of having the Mapnik-AGG patches directly in its own AGG package (because they don't like duplicating system libraries elsewhere).
You either need an AGG library for CentOS that is feature-compatible with the patched Fedora version, or you have to modify your Mapnik build to disable the "system_agg" patch (and drop the "rm -rf boost deps" from the spec file).

You have to check that Cython==0.20 is installed! I had the same issue and that solved it!

setup(

cmdclass = {'build_ext': build_ext},

Cheers
As std::vector is C++ code, you need to set the correct language:
ext_modules = [Extension("kmc_cy", ["kmc_cy.pyx"],language='c++')]
Then g++ should be used instead of gcc and the file name should end with .cpp or .cc.
See this answer for more details.
