why not

  /usr/local/bin:/usr/bin:/home/Edgar/bin:/cygdrive/c/Program
Files (x86)/ISC BIND 9/bin:/cygdrive/c/Windows:/cygdrive/c/Windows/system32

?


I see anyway a /cygdrive/c/usr/bin without cygwin64.

The error could be caused by having a /cygdrive/c/cygwin64/bin = /bin
before /cygdrive/c/cygwin64/usr/bin = /usr/bin

If phython is looking for a relative directory to /usr/bin

See /etc/profile for the default PATH setting.
