A quick workaround would be to add this to the slackbuild.

Code:

sed -i "s|/lib|/lib${LIBDIRSUFFIX}|" build/pkgs/iml/spkg-install

There may be other places that require similar fixes.

This does not work, the build fails with the same error. Unless I don't understand where the build script this command should go - I put it right before "make build".

You will also need to add

if [ "$ARCH" = "i586" ]; then
LIBDIRSUFFIX=""
elif [ "$ARCH" = "x86_64" ]; then
LIBDIRSUFFIX="64"
else
LIBDIRSUFFIX=""
fi

somewhere just after the arch detection section of the slackbuild in order to set LIBDIRSUFFIX.
Also LIBDIRSUFFIX should probably be LIBSUFFIX

This works, it now builds on both vanilla and multilib. Thanks!

you're leaving both blank and only assigning one,

Code:

if [ "$ARCH" = "i586" ]; then
LIBDIRSUFFIX=""
elif [ "$ARCH" = "x86_64" ]; then
LIBDIRSUFFIX="64"
else
LIBDIRSUFFIX=""
fi

why not just do this, if true, do this , else do that.

Code:

[ "$ARCH" = "x86_64" ]  && 
{ LIBDIRSUFFIX="64" ; } || 
{ LIBDIRSUFFIX=""   ; }

#which can be written
[ "$ARCH" = "x86_64" ]  && { LIBDIRSUFFIX="64" ; } || { LIBDIRSUFFIX=""   ; }
or the ole'

if [ "$ARCH" = "x86_64" ] ;
then 
     LIBDIRSUFFIX="64"
else
     LIBDIRSUFFIX=""
fi
