Trying to install on FreeBSD 3.3

[Ralph Dratman]

Hi,

I'm trying to install gprolog-1.2.1 on FreeBSD 3.3. I did

        ./configure
        make

and received the following output:

---------------------------------------------------
(cd EnginePl; make config)
. ./SETVARS;for i in TopComp EnginePl Wam2Ma Ma2Asm Linedit   BipsPl
Pl2Wam Fd2C EngineFD BipsFD;do (cd $i; make) || exit 1; done; (cd
TopComp; make gprolog)
D=`(cd ..;for i in *;do test -d $i && X="$X
/usr/languages/gprolog-1.2.1/src/$i";done;echo $X)`; ./cpp_headers
headers.h gprolog.h $D
*** Error code 1

Stop.
*** Error code 1

Stop.
---------------------------------------------------

Starting from src, I can manually do

        cd TopComp
        make

without any errors, but when I try

        cd EnginePl
        make

I get the same error as shown above, which I don't understand.  Any 
suggestions?

Thanks in advance.
