 Dear CCL Users,
 Please could anyone help me?
 I am trying to execute the Molpro 2009 in a computer with
 Ubuntu 10.04 64 bits (Kernel Version: 2.6.32-28 SMP, and
 libc6 Version: 2.11.1-0ubuntu7.8).
 But the program have been stopped
 and typed the following error:
 /opt/molpro/bin/molprop_2009_1_Linux_x86_64_i8.exe, len=50
 cf3cl_8.inp, len=11
 -master, len=7
 ubuntu, len=6

 Creating: host=ubuntu, user=elizete,
 file=/opt/molpro/bin/molprop_2009_1_Linux_x86_64_i8.exe, port=39720

 Is this a Ubuntu version problem ?
 Please could anyone tell me what is wrong and how can I fix that ?
 Thanks for any help.
 Best Regards,
