Or, think of the PATH as your favorites. An ordered list of places to look for programs.
In your example, there were five BIN directories to search for any referenced programs.
And the BIN directories are where executable programs are typically stored.

NAME
perlcc - generate executables from Perl programs SYNOPSIS
$ perlcc hello # Compiles into executable 'a.out' $ perlcc -o hello hello.pl # Compiles into executable 'hello' $ perlcc -O file # Compiles using the optimised C backend $ perlcc -B file # Compiles using the bytecode backend $ perlcc -c file # Creates a C file, 'file.c' $ perlcc -S -o hello file # Creates a C file, 'file.c', # then compiles it to executable 'hello' $ perlcc -c out.c file # Creates a C file, 'out.c' from 'file' $ perlcc -e 'print q//' # Compiles a one-liner into 'a.out' $ perlcc -c -e 'print q//' # Creates a C file 'a.out.c' $ perlcc -I /foo hello # extra headers (notice the space after -I) $ perlcc -L /foo hello # extra libraries (notice the space after -L) $ perlcc -r hello # compiles 'hello' into 'a.out', runs 'a.out'. $ perlcc -r hello a b c # compiles 'hello' into 'a.out', runs 'a.out'. # with arguments 'a b c' $ perlcc hello -log c # compiles 'hello' into 'a.out' logs compile # log into 'c'. DESCRIPTION
perlcc creates standalone executables from Perl programs, using the code generators provided by the B module. At present, you may either create executable Perl bytecode, using the "-B" option, or generate and compile C files using the standard and 'optimised' C backends. The code generated in this way is not guaranteed to work. The whole codegen suite ("perlcc" included) should be considered very experimen- tal. Use for production purposes is strongly discouraged. OPTIONS
-Llibrary directories Adds the given directories to the library search path when C code is passed to your C compiler. -Iinclude directories Adds the given directories to the include file search path when C code is passed to your C compiler; when using the Perl bytecode option, adds the given directories to Perl's include path. -o output file name Specifies the file name for the final compiled executable. -c C file name Create C code only; do not compile to a standalone binary. -e perl code Compile a one-liner, much the same as "perl -e '...'" -S Do not delete generated C code after compilation. -B Use the Perl bytecode code generator. -O Use the 'optimised' C code generator. This is more experimental than everything else put together, and the code created is not guaran- teed to compile in finite time and memory, or indeed, at all. -v Increase verbosity of output; can be repeated for more verbose output. -r Run the resulting compiled script after compiling it. -log Log the output of compiling to a file rather than to stdout. perl v5.8.9 2009-04-13 PERLCC(1)
