* basic functionality to install spec from a binary cache when it's available; this spiders each cache for each package and could likely be more efficient by caching the results of the first check
* add spec to db after installing from binary cache
* cache (in memory) spec listings retrieved from binary caches
* print a warning vs. failing when no mirrors are configured to retrieve pre-built Spack packages
* make automatic retrieval of pre-built spack packages from mirrors optional
* no code was using the links stored in the dictionary returned by get_specs, so this simplifies the logic to return only a set of specs
* print package prefix after installing from binary cache
* provide more information to user on install progress
* Add bowtie2@2.3.0, fix dependencies and sbangs
Add support for bowtie2@2.3.0
- digest
- a patch for 2.3.0 that parallels the existing package. Truth be
told it builds (for me) without this, but I'm assuming that they're
there for a reason...).
- tune up dependencies
- need tbb
- don't need readline or zlib
Several things were installed with sbang's that use `/usr/bin/env` to
fine perl or python. Fix the dependency and clean up the sbang lines.
* Fix python exe name, avoid path banging
I'd cut and pasted the python bit from the perl bit and missed one
reference to perl.
While I'm there, use the cleaner `spec['perl'].command` instead of
banging together the path from its bits.
* Fix up the "when" constraints on the dependencies
Get the edge cases right.
- 2.2.5 doesn't need tbb, 2.3.[01] do.
- 2.3.1 needs readline and zlib.
The go team released 1.9.2 which includes fixes for some things
that 1.9.1 broke:
> ... include fixes to the compiler, linker, runtime, documentation, go command, and the crypto/x509, database/sql, log, and net/smtp packages. They include a fix to a bug introduced in Go 1.9.1 and Go 1.8.4 that broke "go get" of non-Git repositories under certain conditions.
