Cpanel Shows Blank Page After Login FreeBSD

On 5.4-RELEASE FreeBSD 5.4-RELEASE server, After login to cpanel, i get blank page.

I checked log file /usr/local/cpanel/logs/error_log, it shows error

/usr/libexec/ld-elf.so.1: Cannot open "/usr/local/lib/compat/libm.so.2"

I tried following, but do not helped.

# /scripts/upcp --force
# /scripts/fixeverything

Also downloaded perl from cpanel site (http://layer1.cpanel.net) and installed it, but it do not fixed the error.

The problem is solved by upgrading "compat4x-i386-5.3" program.

First i upgrade ports with portsnap

# portsnap fetch
# portsnap extract

Now upgrade compat4x-i386-5.3 with portupgrade command.

# portupgrade compat4x-i386-5.3

Now the cpanel start working.
