To evoke a package installed on HD

[satimis]

Hi folks,

FC3
LFS LiveCD

Would it be possible from LiveCD to evoke a package installed on HD ?

LFS LiveCD only has basic packages installed unable to read .pdf and .doc/.rtf files. I imagine whether I can evoke OpenOffice/Xpdf/Acrobat_Reader from the LiveCD. They are installed on FC3 HD

I performed following test without success.

OOwriter is evoked on FC3 with;
/usr/bin/oowriter

While running LFS LiveCD
On console
# su -
# mkdir /mnt/hd2
# mount /dev/hda2 /mnt/hd2
# cd /mnt/hd2
# chroot /
# /usr/bin/ could not locate "oowriter". It seemed disappeared.

Is there any method. TIA

B.R.
