libdv fails on Darwin/x86

[Davide Zanon <d.zanon%infinito.it@localhost>]

Hello! I'm trying to compile multimedia/libdv on Darwin/x86 8.8.1
and it fails in what I suppose is assembly stuff this way:

if /bin/sh ../libtool --silent --mode=compile --tag=CC gcc -pipe - 
DHAVE_CONFIG_H  -I. -I. -I..   -no-cpp-precomp -I/usr/pkg/include - 
D_REENTRANT -I/usr/include   -O2 -I/usr/pkg/include -D_REENTRANT -I/ 
usr/include -Wall -g -MT enc_output.lo -MD -MP -MF ".deps/ 
enc_output.Tpo" -c -o enc_output.lo enc_output.c;  then mv -f ".deps/ 
enc_output.Tpo" ".deps/enc_output.Plo"; else rm -f ".deps/ 
enc_output.Tpo"; exit 1; fi
/bin/sh ../libtool --silent --mode=compile gcc -pipe   -O2 -I/usr/pkg/ 
include -D_REENTRANT -I/usr/include -c -o vlc_x86.lo vlc_x86.S

*** Error code 1

Stop.
bmake: stopped in /usr/pkgsrc/multimedia/libdv/work/libdv-0.104/libdv
*** Error code 1

I don't know anything about this, is there any way I could help?
Thank you very much!
