This should be adding memory and basement to RDEPEND as you can see in the .cabal file:

  Build-depends:     bytestring
                   , memory >= 0.14.18
                   , basement >= 0.0.6
                   , ghc-prim

---

Could it have something to do with this conditional Buildable: False in the library stanza?

  if impl(ghc < 8.8)
    Buildable: False
  else
    Build-depends:   base

Yep, it works fine if you take that stuff out:

It is also worth mentioning the virtual/libc in RDEPEND seems pointless.

(New bug: #117)

[hololeap]

It looks like this bug also stems from a conditional buildable: False in the .cabal file:

    if impl(ghc < 8.6)
        buildable: False

[hololeap]

Also seems related:

The problem is not in multiple stanzas, but in a version-specific guard:

  if !impl(ghc >=8.0)
    buildable: False

hackport starts off with ghc-7 and settles on an older ghc version with subset of tests disabled.

#81 (comment)

[hololeap]

f4cf447 addresses the most egregious case, where an entire library in a package is marked with buildable: False (usually inside if impl(ghc<X)). It will now throw an error if a library is marked unbuildable and display a warning for executables and test-suites.

[hololeap]

dd883f1 raises the minimum version of GHC that hackport will consider.

Many of these if impl(ghc<X) expressions in .cabal files are strictly for compatibility with old versions of GHC. If hackport chooses a version of GHC that is too old, the ebuild will be generated based off this version of GHC and may pull in dependencies that are meant as compatibility options.
