Bug 813651

suggested patch on .spec file

Description of problem:
bash-completion contains in completions one shell script and three other symlinks called *.py. rpmbuild tries to run /usr/lib/rpm/brp-python-bytecompile on those scripts with disasterous results:

+ /usr/lib/rpm/brp-python-bytecompile /usr/bin/python 1

(tried also in koji http://koji.fedoraproject.org/koji/taskinfo?taskID=4000853)

Version-Release number of selected component (if applicable):
bash-completion-1.99-1.fc18

How reproducible:
100% (even in koji)

Steps to Reproduce:
1.rpmbuild --rebuild bash-completion-1.99-1.fc18.src.rpm
2.
3.
  
Actual results:
build fails

Expected results:
it shouldn't

Additional info:
As bash-completion really doesn't contain any true Python scripts, the best line of attack is IMHO just to switch of bytecompilation of Python scripts (see https://fedoraproject.org/wiki/Packaging:Python#Bytecompiling_with_the_correct_python_version) by adding this redefinition to the top of the spec file (on one line):

%global __os_install_post %(echo '%{__os_install_post}' | sed -e 's!/usr/lib[^[:space:]]*/brp-python-bytecompile[[:space:]].*$!!g')
