[Cin] Compile on Arch (only a curiosity)

[Andrea paz]

I can't compile the last 2 release.
The configuration and make steps are fine, but I have an error in the
"make install" step:

[...]
cp -a COPYING README models Cinelerra_factory expanders.txt \
        shuttlerc ffmpeg msg info tips lv2_blacklist.txt bin/.
sed -e 's/\<cin\>/cin/g' < image/cin.desktop \
        > "bin/applications/cin.desktop"
cp -a image/cin.svg "bin/pixmaps/cin".svg
cp -a image/cin.xpm "bin/pixmaps/cin".xpm
mkdir -p bin/plugins/picon/cinfinity
for d in picon/*; do \
  if [ $d = picon/cinfinity ]; then continue; fi; \
  cp -a $d bin/plugins/picon/.; \
done
cp -a db/utils/new_db "bin/cin_db"
cd bin; /home/paz/cinelerra5/cinelerra-5.1/inst.sh "/usr/bin" \
        zmpeg3{cat,cc2txt,ifochk,show,toc}
cp: impossible to create the regular file '/usr/bin/zmpeg3cat':
Permission denied
make: *** [Makefile:977: zmp_install] Error 1

If I compile using ./bld.sh instead, there are no errors.
(All the installations I did were non-root.)
