deb creation failure with --enable-headless in git master

Hello,

with this configuration:

./autogen.sh --enable-headless --enable-epm --without-doxygen

i get this error on ubuntu 12.04 lts:

I thought it could be missing files but this script

for x in $( grep ^f 
/home/rm/src/libo/workdir/unxlngx6.pro/installation/LibreOffice_Dev/deb/listfile/en-US/epm_gid_Module_Root.lst
 | grep -o "/home.*$" ) ; do test -e $x || echo $x ; done

does not give output

and running this manually

LD_PRELOAD=/home/rm/src/libo/solver/unxlngx6.pro/lib/libgetuid.so /usr/bin/epm -f deb  -g 
lodevbasis4.2-core01 
/home/rm/src/libo/workdir/unxlngx6.pro/installation/LibreOffice_Dev/deb/listfile/en-US/epm_gid_Module_Root.lst
 --output-dir DEBS -v  2>&1

does not give any more help.

Any hint?

thanks in advance,
riccardo
