fcron won't install; during ./configure I get this:
configure: WARNING:

/usr/share/sgml/docbook/stylesheet/dsssl/modular/html/docbook.dsl does not exist. You will probably not be able to generate the documentation from the DocBook source files.
configure: WARNING: Use --with-dsssl-dir to specify a directory.

and then during checkinstall I get this:
make[1]: Entering directory `/home/william/temp/fcron-3.0.1/doc'
shell-init: error retrieving current directory: getcwd: cannot access parent directories: Invalid argument
chdir: error retrieving current directory: getcwd: cannot access parent directories: Invalid argument
pwd: error retrieving current directory: getcwd: cannot access parent directories: Invalid argument
Cleaning:
/bin/sh: line 7: cd: .: No such file or directory
/bin/sh: line 3: cd: en: No such file or directory

I don't know what these mean, anyone install this app successfully?

Sounds like you need to install linuxdoc-tools.

Solved.
I used ./configure --with-answer-all --with-pam=no --with-selinux=no ./configure --with-answer-all --with-pam=no --with-selinux=no --with-fcrondyn=no
and used make install instead of checkinstall.

It installed OK and is running now.
As usual, I don't know why it needed --with-fcrondyn=no, and/or make install instead of checkinstall.
