Another command that might be available and also works quite well for this is 'blkid'. It's part of the e2fsprogs package. Examples of it's usage:
Look up data on /dev/sda1:
topher@crucible:~$ sudo blkid /dev/sda1
/dev/sda1: UUID="727cac18-044b-4504-87f1-a5aefa774bda" TYPE="ext3"
Show UUID data for all partitions:
topher@crucible:~$ sudo blkid
/dev/sda1: UUID="727cac18-044b-4504-87f1-a5aefa774bda" TYPE="ext3"
/dev/sdb: UUID="467c4aa9-963d-4467-8cd0-d58caaacaff4" TYPE="ext3"
Show UUID data for all partitions in easier to read format:
(Note: in newer releases, blkid -L has a different meaning, and blkid -o list should be used instead)
topher@crucible:~$ sudo blkid -L
device fs_type label mount point UUID
-------------------------------------------------------------------------------
/dev/sda1 ext3 / 727cac18-044b-4504-87f1-a5aefa774bda
/dev/sdc ext3 /home 467c4aa9-963d-4467-8cd0-d58caaacaff4
Show just the UUID for /dev/sda1 and nothing else:
topher@crucible:~$ sudo blkid -s UUID -o value /dev/sda1
727cac18-044b-4504-87f1-a5aefa774bda

The epoll "library" is a set of system calls that should be already available in your kernel (it was introduced in kernel 2.5.44). If you are getting a specific error in compilation, you should provide it in your question so more specific assistance can be provided.
