Solution 1

You need to pass the path to the boost directory with a -I option.
If the boost directory exists as /users/boost, you need to specify -I"/users".

Can you give me an example of how to correct this? I am new to this and I don't know how to solve it exactly. I downloaded boost and then re-ran the same function (make -f makefile.osx USE_UPNP=-) and got a new error.

It's basically the same error.
File not found for a #include means that you're not specifying the path where the file exists with the -I option.

oh ok. it says to include gmpxx.h but it got cut off next to the #include. would the code look like this

-I gmpxx.h make -f makefile.osx USE_UPNP=-

No. -I is to specify the directory.
Assume gmpxx.h exists in the /usr/ethan/inc directory.
If you do a #include <gmpxx.h> in your code, you would need to use -I /usr/ethan/inc for the make command line.
