Description of problem: The symbol 'atan2' is undefined in $libdir/liba2ps.so.1. This will cause an application crash if referenced.

Version-Release number of selected component (if applicable):

How reproducible: every time

Steps to Reproduce:
1. readelf --symbols /lib*/liba2ps.so.* | grep atan2
Actual results:
    24: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND atan2

Expected results: No unresolved symbols

Additional info: Fix is: add "-lm" to the libraries when building liba2ps.so.1.
Comment 1 John Reiser 2012-04-03 22:24:09 EDT
Additional piece that is needed to confirm this is a bug:
  $ ldd /lib*/liba2ps.so.1
	linux-vdso.so.1 =>  (0x00007fffac58b000)
	libc.so.6 => /lib64/libc.so.6 (0x0000003d97400000)
	/lib64/ld-linux-x86-64.so.2 (0x0000003d97000000)
which does not include libmath (-lm).
