Check the makefile to see if there is a variable you can add to
include that path.
Otherwise, man make and check the script that makes the plugin, e.g.
you will want to add:

make -I /usr/include/nspr4

Another option (may be easier)

export C_INCLUDE_PATH=/usr/include/nspr4:$C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH=/usr/include/nspr4:$CPLUS_INCLUDE_PATH

Then re-try the make.
