Description of problem:
guile-devel depends on libtool-ltdl-devel, but this is not set as an rpm requirement for that package.

guile-devel's pkgconfig script adds -lltdl to the linker flags of any package that wants to build against guile. However the package that provides libltdl (libtool-ltdl-devel) is not automatically installed, hence an attempt to build your code will fail.

Version-Release number of selected component (if applicable):
guile-devel-1.8.7-6.fc14.i686

How reproducible:
Always

Steps to Reproduce:
1. yum remove guile-devel and libtool-ltdl-devel
2. yum install guile-devel
=> note that libtool-ltdl-devel is not pulled in as a dependency
3. Try to build a package that requires guile-devel, like for example gnucash
=> note that it will fail because -lltdl can't be found
