In principle, just unpacking the cabal-install package and running 
bootstrap.sh is far far easier.

You seem to not have libdl.so, which is needed by the unix package.
Can you confirm this by running

$ locate libdl

(or

$ ls /usr/lib | grep libdl
$ ls /lib | grep libdl

if you don't have [the rights to run] locate)?
If that doesn't show something like

/lib/libdl-2.9.so
/lib/libdl.so.2
/usr/lib/libdl.a
/usr/lib/libdl.so

, you'll have to install glibc-devel, which provides /usr/lib/libdl.a and 
/usr/lib/libdl.so (the others are provided by glibc, but I can't imagine 
that you haven't that installed).
And while you're in YaST, installing software, grab almost every *-devel 
package you see, unless you're sufficiently sure that you will not need 
that one - installing one more devel-package a week becomes annoying pretty 
soon.
