applications we wrote run on Solaris exclusively. all the modules and plugins are installed out of solaris packages. i.e we have to wait for the unix team build and install it for us first. aparently they are busy as hell and the difficulities of installing Perl modules usually make things worst. thus a request may take weeks to finish.
for the pure Perl module, this is not much issue. we just drop it to our common lib directory.
today i need Text::CSV_XS to parse lots of CSV files. but alas.. it is XS.
i am glad that Perl usage at my workplace is going up. but this just slows thing down. another example, the mod_perl request's been in the queue for two weeks
