The problem is cmake's way to figure out what nasm it has got:
==== /usr/share/cmake/Modules/CMakeDetermineASMCompiler.cmake:79 ====
list(APPEND CMAKE_ASM${ASM_DIALECT}_COMPILER_ID_VENDORS MSVC )
set(CMAKE_ASM${ASM_DIALECT}_COMPILER_ID_VENDOR_FLAGS_MSVC "/?")
set(CMAKE_ASM${ASM_DIALECT}_COMPILER_ID_VENDOR_REGEX_MSVC "Microsoft

Workaround2: if you have dev-lang/yasm installed, use:
ASM_NASM=/usr/bin/yasm [ebuild|emerge] ...
Workaround3: delete those MSVC lines from
/usr/share/cmake/Modules/CMakeDetermineASMCompiler.cmake
Workaround4: patch cmake-utils.eclass to add
-DCMAKE_ASM_NASM_COMPILER_ID=GNU to cmakeargs in
cmake-utils_src_configure.
HTH,
-dnh, I'd prefer solution 3 ;)
