clisp port problem in 6.1-release amd64

[Gautham Ganapathy]

Hi,

I am trying to install clisp in the fbsd-6.1-release for amd64. When i
give a 'make install clean', it give the following errors and stops

<errors>

intsqrt.d:292: warning: statement with no effect

*** Error code 1

Stop in /usr/ports/lang/clisp.

</errors>

What could be causing this error?

I am unable to install the package either, since 'pkg_add -r clisp' is
unable to find a package.
