I'd like to build latest lirc package for 12.04 with two patches from http://bit.ly/17779VW to make USB Infrared toy v2 work:

Running sudo apt-build source lirc gave me

?  build  ll
total 960
drwxr-xr-x 10 root root   4096 Nov  5 07:07 lirc-0.9.0
-rw-r--r--  1 root root 113909 May  5  2011 lirc_0.9.0-0ubuntu1.debian.tar.gz
-rw-r--r--  1 root root   1553 May  5  2011 lirc_0.9.0-0ubuntu1.dsc
-rw-r--r--  1 root root 857286 May  5  2011 lirc_0.9.0.orig.tar.bz2

in /var/cache/apt-build/build. Running sudo apt-build build-source lirc then gave me Some error occured building package which is not really informative.

I have successfully built patched lirc from source but now I would like to get a deb package. Where can I look for this 'some errors' in detail?

Thank you,

Alexei
