Got more verbose logging out (replaced real IPs with x.xxx):

A temp-inplace file is created by flymake, reading the above it seems
that this is a path issue, or is that wrong? I tried adding
/var/www/blog to $PATH in ~/.shrc and ~/.bashrc on the remote host,
and also customized "Tramp Remote Path" but none of those worked
yet...
