That error is because you don't have libfixposix installed on your
machine.  libfixposix is a library being written by Stelian Ionescu,
the author of IOLib, to unify some POSIX behavior across various unix
machines. It is a C library which is compiled and installed seperately
from IOLib or any other Common Lisp installation.

It is found here:
http://gitorious.org/libfixposix/libfixposix 

You can get a copy of it by:
git clone git://gitorious.org/libfixposix/libfixposix.git

Then make && make install as root.

Afterwards, the build of IOLib in SBCL should work.

However, I know from talking to Stelian recently that the changes to IOLib
to support libfixposix are not yet complete.

I would recommend you use the 0.7.2 version of IOLib until he finishes with
the libfixposix changes.

You can find that here:
http://common-lisp.net/project/iolib/download.shtml

Or, you can dig around in the git log of IOLib (if say you got it via
clbuild or manually getting the head of the branch via git clone) until
you find the SHA1 in which he made the 0.7.2 release and git reset --hard
to that SHA1.

Have a nice day.
