Description of problem:

1) Configure fails if the value of RPM variable %{distribution} consists of more than 1 word. When parsing the args list of configure the second word is taken as an argument of configure (outside "-Dcf_by=%{distribution}" value) and all the following args are ignored. What is generated is wrong.

Solution: turn -Dcf_by=%{distribution} into -Dcf_by="%{distribution}"

2) A 2nd install immediately following a first one (without anything else in between) fails because the directory created by the 1st install is not removed and cmds such as "ln -s" (without "f") or "mkdir" (without "-p") fail

Solution: either remove build root as the 1st operation or turn some "ln -s" into "ln -sf" and "mkdir" into "mkdir -p"

3) Test of perl fails if built with static libperl (as a consequence of point 1) because of many undefined symbols from perl modules used in rebuilding the just deleted perl (CCDLFLAGS is empty : "-Wl,E" is not used by the rebuild and needed symbols are no more exported). If libperl is a dynamic library, deleting and rebuilding perl before (and after) test is useless because LD_LIBRARY_PATH is set to the right value (which override the "rpath" if any). See the value of "RUN_PERL" and LDLIBPTH" in Makefile (they are used to start the tests)

Solution: the content of "%check" can be as simple as 'RPM_BUILD_ROOT="" TEST_JOBS=%{nbprocs} make test_harness_notty'. This works fine in both cases (static or dynamic libperl)

Version-Release number of selected component (if applicable):
5.16.3-1.mga3 (and may be beyond)

How reproducible:
Very easily

Steps to Reproduce:
1.Start a perl rebuild using a 2 words value for "%{distribution}" (points 1 & 3)
2.Try 2 consecutive install operation (point 2)
3.
