Using Relative seems to be unable to find a certain file or another,

same goes for when using absolute, is there something for python I am missing? some sort of compatibility?

Found the issue, it had to do with the default location of gpg (wish when pius setup.py is ran it gets the gpg location from PATH or can be read from a .pius-keyring-mgr config type config)

EDIT: Found a way to have the path for gpg and gpg2 to be found (gpg2 will be the first choice and gpg is second, and then /usr/bin/gpg if none are found), will work on getting a pull request in place that reflects the changes

EDIT 2: #103 Should fix this for others, it is in the 3_work for the future release.

You can pass in -g to specify the path. I'm happy to have per-OS hard-coded lists, but given we're a security application dealing with private keys, we will not execute gpg out random PATHs.

[F9Alejandro]

There is hard coded paths for linux and unix, a binary constant for /usr/bin, /usr/local/bin, /usr/sbin, /usr/local/sbin, /bin, and /sbin. which should cover both OSes and where they like to install to, meaning it is no longer a random path but will check in normal binary paths.

Normal which function can be used for windows, then just check the string returned to see if it contains "gpg4win..\gnupg\bin" in it, if it does then it is a valid install and should be used as this is what gpg4win uses in system path. (I uses gpg4win on my windows computer, and gpg toolset for macOS. I also have a little linux server box for testing purposes and doesn't have remote access unless given access via ssh v2)
