'make' error

ok. hi i'm new to this list. all i want to do is get a little more help 
getting bopm compiled and installed.

[bopm version : 3.1.2]
[gmake version : 3.80]
[gcc version : 4.0.0]
need any more version numbers, let me know.

first. ./configure worked fine. no complaints.

ok this is where im stuck. on 'make'
