This randomized phase II trial is studying how well giving sorafenib together with either temsirolimus or tipifarnib works in treating patients with stage IV melanoma that cannot be removed by surgery. Sorafenib, temsirolimus, and tipifarnib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sorafenib and tipifarnib may also stop the growth of tumor by blocking blood flow to the tumor. It is not yet known whether sorafenib is more effective when given together with temsirolimus or tipifarnib in treating patients with malignant melanoma.
