 I guess the missing datapoint is:
 
 $ ls -l /emul/linux
 lrwxr-xr-x  1 root  wheel  19 Apr 23 21:21 /emul/linux -> /usr/pkg/emul/linux
 
 So the actual path with symlinks expanded is:
 /usr/pkg/emul/linux/usr/local/lib/../../../../../libexec/uvscan/liblnxfv.so.4
 
 Which is expected to contract to:
 /usr/pkg/libexec/uvscan/liblnxfv.so.4
 
 Unfortunately I coded namei() so that ".." at the emulation root always
 goes to the real root, so it ends up being:
 /libexec/uvscan/liblnxfv.so.4
 
 Which won't exist!
 
 Of course, expecting to find a linux binary in /usr/pkg/libexec is rather
 stupid - as another emulation (eg the linux32 one on an amd64 system)
 would also look in the same directory and open the same file.
 
 The package probably ought to be using /emul/linux/libexec.
 
 I'll look at changing namei() though.
