Probably would work. I had a close look at one of the test programs:

frb15@BlueFerniMac1
~/Desktop/Gentoo/var/tmp/portage/sci-libs/lapack-reference-3.3.1-r1/work/lapack-reference-3.3.1_build/bin
$ ./xeigtstc
dyld: Library not loaded: /Users/frb15/Desktop/Gentoo/usr/lib/libtmglib.dylib

   Reason: image not found
Trace/BPT trap
frb15@BlueFerniMac1
~/Desktop/Gentoo/var/tmp/portage/sci-libs/lapack-reference-3.3.1-r1/work/lapack-reference-3.3.1_build/bin
$ ls ../lib/
libreflapack.dylib  libtmglib.dylib

In short it is linked as if it was installed. So it doesn't find one of its
essential library. I am not quite sure how to fix this - in a general fashion.
I think I may be able to do something on OS X. It may actually be easier on a
linux prefix by using LD_LIBRARY_PATH. But the real solution would be for the
test run to have different linking options.
