Caveat #1: I've never used a Hackintosh, but the output you gave 
screenshots for (which would be more useful if they were copy-and-pasted 
into the body of the email) look like common scripting errors, not in a 
C program, but rather a bash or sh script.  In addition, the file 
extensions, while never conclusive about a file's content, also point to 
those files being bash or sh scripts.

Caveat #2: Not being able to view those scripts, I'm going on very slim 
evidence.  So....   I'm guessing that install.sh isn't working because 
the binaries aren't present on your system.  One error message gave a 
subtle hint in that direction.  This means (again, guessing) that 
compile.sh needs to be run.  However, doing that gave you a common error 
message, i.e., about a "unary operator expected".  If you look inside of 
those files and specifically at the line numbers cited in the error 
message, you should see that "-eq" operator.

The reason for the error (not seeing the content of those files, again, 
I'm guessing) is probably because some variable in a comparison 
operation is undefined or empty.  (To a small extent this is a coding 
error: the script should instead check the value of this variable and 
produce a better error message rather than simply horking.  So note to 
devs.)

You might be able to get the compile.sh and then the install.sh scripts 
to work by supplying an argument to each... the absence of that argument 
could be the missing variable value.  To actually know, read the 
documentation which came with those two files, e.g., anything like 
README or INSTALL.doc etc.  Moreover, to do most of the above more 
easily, you should probably open a terminal window, which will give a 
persistent system prompt and allow entering a series of system commands, 
rather than clicking on filenames.  Once in a terminal window, navigate 
to the directory where the relevant files are located (using the "cd" 
command), display the names of the files and directories (using the "ls" 
command), and view the contents of the desired files, those mentioned 
above (with either the "less" or "more" commands).  Once you're 
comfortable with those things and you've found the problem (perhaps by 
reading the documentation), then you can try again to run "su - 
./compile.sh" and then "su - ./install.sh" and see what happens.
