Help installing PDFtk on Mac Leopard

Ok did some research found the following...

*"After unpacking pdftk, change into the pdftk directory and run make -f Makefile.MacOSX. It will take awhile to finish compiling. When it is done, move the resulting pdftk program to a convenient location in your $PATH, such as /usr/bin."*

I've compiled everything, but don't understand the the last comment about "moving the resulting pdftk program to a convenient location in your $PATH, such as /usr/bin"

I'm new to using terminal and only understand some of the basic functions. any help would be greatly appreciated

thank u

Ok check my directories.

the pdftk executables where installed

/opt/local/bin/

I think the $Path for user is /usr/bin/

do i need to move the pdftk executable files to the /usr/bin or include the /opt/local/bin in the user $Path.

plus, i checked out the .proflile in my user home directory and this is what it says....


#
*# Your previous .profile (if any) is saved as .profile.mpsaved*
*# Setting the path for MacPorts.*
*export PATH=/opt/local/bin:/opt/local/sbin:$PATH*


what does this mean?

One more thing...

I used Port Authority app to install pdftk this the info it gave

Port pdftk contains:
/opt/local/bin/pdftk
/opt/local/share/doc/pdftk/pdftk.1.html
/opt/local/share/doc/pdftk/pdftk.1.txt
/opt/local/share/man/man1/pdftk.1.gz

not sure how to interpret this...

thank you
