postgres/perl problem in 7.3b5

I posted this to general because I'm fairly sure it's my problem, not
postgresql's.

I put my build errors below.

It looks to me like maybe I have a bad perl development package. Does anyone
else have this problem? I am on debian unstable and x86, using perl 5.8.

Oh, and same thing for beta3 also.

Regards,
    Jeff
