Oh okay i will, and im on both linux and Windows using cygwin thanks ill give it a tryit depends on your system... on linux or macOS, the default installation for the toolchain and PSL1GHT will be:
/usr/local/ps3dev
Then the pkgi source can be in any folder, like /home/projects/pkgi-ps3 . As long as your environment has the variables and paths, you'll be able to compile it.
(For simplicity, I suggest to use one of the precompiled toolchains+psl1ght builds I have published on GitHub.)
