Error trying to build Balsa 1.3.6

[Paul Lewis <paul lewis karachi freeuk com>]

I have just tried to build balsa 1.3.6 on redhat 7 . The
following are snippets from the confgirue script and make script
outputs.
The first seems to work fine, but the latter ends with the error
displayed. Can anyone give me a hint as to what could be the problem?
