The difficulty here is this: liblapack is useless without _some_ 
form of libblas (BLAS = Basic Linear Algebra System), but there 
are various blas's.  There's the libblas from the same (netlib) 
source as lapack itself, and there are versions that are tuned for 
best performance on a specific processor.  I'd say that it's 
really up to the OS/distro to ensure that if you choose to install 
lapack, some suitable form of blas is pulled in as a dependency.

Or in other words, this seems like a Fedora packaging bug to me.

So far as the configure script is concerned, then, gnome is OK.

[ plus more "skipping incompatible" messages for gnome-related 
libraries.]

But so far as the linker is concerned, gnome is a mess!  Very 
weird.  What's wrong with your gnome libraries that the linker 
finds them "incompatible"?  Is this a 64-bit system?

You could try passing the option "--without-gnome" to configure 
(or put it in the .spec file), since the linker is not barfing on 
the other libraries that gretl wants.  And in fact, you don't lose 
much by dropping the gnome linkage.
