lam requires libaio.so.1 but really needs libaio.so

Description of problem:
If you have the lam and libaio packages installed, but not libaio-devel, then
hf77 returns the error
/usr/bin/ld: cannot find -laio
collect2: ld returned 1 exit status
The problem is that although libaio.so.1 is in the requires list for lam (which
is provided by the libaio package), hf77 actually looks for libaio.so - a
symbolic link to libaio.so.1, which is in the libaio-devel package.
Either the requirements of the lam package should be changed, or the libaio and
libaio-devel packages should be reorganized.
"libaio-devel" (with the .so for linking) is needed to compile programs, not to
run lam. Same with gcc-g77 - if you're going to compile, and not have it be a
node, you need all the libraries/programs you'll use to create that program.
That would be fair enough if you got the option not to use the aio library, but
you don't - it is added automatically. You need libaio-devel to use hf77 at all,
even if you are only building a hello world program. Try it!
It's optional for running a program. It's in the same category as a complete set
of compilers, glibc-devel, libstdc++-devel etc. if you use it to build programs
- and you'll notice that e.g. gcc doesn't require all the "-devel" packages in
the distribution even though you could get the same compile errors you're seeing
I wouldn't expect gcc to require all the -devel packages in the distribution,
but I would expect it to require any -devel packages that are needed even to
compile the simplest of programs, which is the case with hf77 and libaio-devel.
