Comment(by drkirkby):
Here is some results when installed on my IBM RS/6000, which runs AIX 5.3.
{{{
-bash-4.1$ uname
AIX
}}}
Here's the output after running "make" on the AIX system, which has the
maths library installed, since the bos.adt fileset was installed.
{{{
-bash-4.1$ uname
AIX
-bash-4.1$ make
<snip irrelevant output>
Starting prerequisite check.
Machine: AIX aixbox 3 5 000245984C00

checking for sqrt in -lm... yes
checking for sqrtl in -lm... yes
configure: creating ./config.status
config.status: creating Makefile
config.status: creating config.h
config.status: executing depfiles commands
}}}
Then I removed the maths library, /usr/lib/libm.a.
{{{
-bash-4.1$ su
root's Password:
# mv /usr/lib/libm.a /usr/lib/foo
# exit
}}}
Then after running make, we see that the 'prereq' script exits with an
error.
{{{
checking for sqrt in -lm... no
configure: This system has no maths library installed.
configure: On AIX, this is in the bos.adt.libm fileset.
configure: Actually, we recommend to install the complete bos.adt fileset.
configure: This needs to be performed by a system administrator.
configure: error: Exiting, since a maths library was not found.
ERROR: You do not have all of the prerequisites needed
to build Sage from source. See the errors above.

}}}
Finally, I did manage to remember to restore my maths library!
{{{

# exit
-bash-4.1$
}}}
