(In reply to amyascwk from comment #1) > Created attachment 516942 [details, diff] [details, diff] > patch to include -lm library during configure I also encounter the same build error for sci-libs/libctl-3.2. The attached patch includes the -lm library during configure, as suggested by upstream in https://github.com/stevengj/libctl/issues/1. With this change it manages to build successfully.
Package removed.
