cabextract error trying to upgrade amavisd-new

[Robert Fitzpatrick]

I am trying to do the portupgrade of amavisd:

 portupgrade -o /usr/ports/security/amavisd-new amavisd-new-20030616.p9

and getting the following error as it tries to build the required
cabextract port:

esmtp# make all install
===>  Building for cabextract-1.1
make  all-am
cc -DHAVE_CONFIG_H -I. -I. -I.  -I./mspack -DMSPACK_NO_DEFAULT_SYSTEM   
-O -pipe -mcpu=pentiumpro -c fnmatch.c
fnmatch.c:48:24: safe-ctype.h: No such file or directory
*** Error code 1

Stop in /usr/ports/archivers/cabextract/work/cabextract-1.1.
*** Error code 1

Stop in /usr/ports/archivers/cabextract/work/cabextract-1.1.
*** Error code 1

Anyone know what I should do for this error?
