Config_heavy-target.pl has the same content as I gave for config.sh.

I did this as a test:
bitbake -cclean perl perl-native libdatetime-perl
libdatetime-perl-native; bitbake libdatetime-perl

results: config.sh and Config_heavy-target.pl are as reported before.
Build fails. Info on the file:

Obviously the settings from config.sh are not taken into account.

target sheevaplug (armv5t5) distro minimal, git head of a few days
ago. litbool 2.4 with sysroot support.

Roman, can you perhaps retest with qemu-arm and minimal (as Khem
suggested in the next message).
Also I'm more than happy to do additional tests and/or compare notes
on irc (e.g. tomorrow evening european time)
