[with patch; positive review] cvxopt-0.9.p7: build failure due to missing perl modules

[tornaria]

The error reported by cvxopt-0.9.p7 is:

Can't locate File/Copy.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at ./spkg-install line 2.
BEGIN failed--compilation aborted at ./spkg-install line 2.

I did have perl installed in the system, but only the perl-base package (5.10.0-19, debian/lenny).

However, the File/Copy.pm module is in perl-modules package, which wasn't installed in my system (perl-base priority is required, and perl-modules priority is standard).

The workaround was to apt-get install perl-modules; maybe this issue with File/Copy.pm could be checked in the prereq spkg?

The real fix here is to get rid of the dependency since it is introduced by the Fortran library handling code written by Josh Kantor. The spkg-install should just be a shell script instead of a perl script given that we only copy two different setup.py files depending on the Fortran runtime used.

Cheers,

Michael

patch for cvxopt-0.9.p7.spkg: replace spkg-install perl script by a bash script, eliminating the dependency on perl

[tornaria]

With the patch above, compilation of 3.4.1 was successful in a minimal debian lenny chroot created with debootstrap (minimal install) + apt-get install make gcc g++ m4 inside the chroot.

See also #5964; it turns out building R documentation also requires perl-modules. Compilation of Sage proceeds without it, but some doctests (which use R documentation) fail. IOW, it seems perl-modules is a requirement for compilation after all...

Looks good to me.
