wsgen, wsimport man pages error

Displaying wsgen and wsimport man pages included in promoted b98, following error occured and the whole tables are not displayed. Both man pages have 2 tables each. Pages were rendered okay on Solaris. This is happening on RedHat EL 4.

[so129345@lager rc]$ man -M ./man wsgen
/usr/bin/gtbl:<standard input>:45: `.' not last character on line
/usr/bin/gtbl:<standard input>:45: giving up on this table
/usr/bin/gtbl:<standard input>:599: `.' not last character on line
/usr/bin/gtbl:<standard input>:599: giving up on this table

[so129345@lager rc]$ man -M /import/near/Duke/jdk1.6.0/test/man/rc/man wsimport
/usr/bin/gtbl:<standard input>:72: `.' not last character on line
/usr/bin/gtbl:<standard input>:72: giving up on this table
/usr/bin/gtbl:<standard input>:641: `.' not last character on line
/usr/bin/gtbl:<standard input>:641: giving up on this table

I'm referring to following documents and seems lost tables have quite a information.
