Trouble compiling under ubuntu 10.04

[Parker Jones]

Hello,

Has anyone else had difficulty compiling gprolog 1.3.1 under Ubuntu 10.04 on i686?

After ./configure and make, I get

gplc -o pl2wam --no-fd-lib --min-bips pl2wam.o read_file.o bip_list.o syn_sugar.o internal.o code_gen.o reg_alloc.o inst_codif.o first_arg.o indexing.o wam_emit.o
make[1]: Leaving directory `/home/parker/Downloads/gprolog-1.3.1/src/Pl2Wam'
make[1]: Entering directory `/home/parker/Downloads/gprolog-1.3.1/src/Fd2C'
gplc -c --fast-math fd2c.pl
fd2c.pl:215-220: fatal error: exception raised: error(instantiation_error,sort/2)
compilation failed
make[1]: *** [fd2c.o] Error 1
make[1]: Leaving directory `/home/parker/Downloads/gprolog-1.3.1/src/Fd2C'
make: *** [all] Error 1
address@hidden:~/Downloads/gprolog-1.3.1/src$

I can supply the full log if it helps.

Cheers,
Parker
