[config-package-dev] transform does not work on ubuntu trusty

[Djokic, Slavisa]

Hello Jonathan,

i guess Build-Depending on config-package-dev means it's listed in Build-Depends in the control file. Yes, as all examples show I've put config-package-dev in there. Is this wrong?

Hi Sascha, 

Please be sure to CC config-package-dev at mit.edu so that the other maintainers see the entire thread.

Are you Build-Depending on config-package-dev?  That might explain why pbuilder can't find it.

You may want to check out the examples in /usr/share/doc/config-package-dev/examples/debhelper/  (Assuming you have installed config-package-dev)

However, that's probably also a bad idea, since patch will still look for the source file (to be patched) on the filesystem.  There is, as far as I can tell, no good way to get patch to use stdin as the original (to-be-patched) file.
