changes usage of lround into (long int)rint

this change was proposed on the freebsd mailing list :
http://lists.freebsd.org/pipermail/freebsd-ports/2005-March/021434.html

ebuild uses the previous patch

[Comment 3 SpanKY 2005-10-13 18:05:58 UTC]

went with the upstream fix instead which is to use round() instead of lround()
