Why not just use rpm to remove your current install of quota and re-compile it from source, unless it is a kernel bug it should either run stable or die on compile? There is a perl Quota module BTW but that is just an interface onto quota AFAICT.

There are four major species of Unix sysad

1. The TECHNICAL THUG. Usually a systems programmer who has been forced into system administration; writes scripts in a polyglot of the Bourne shell, sed, C, awk, perl, and APL.
2. The ADMINISTRATIVE FASCIST. Usually a retentive drone (or rarely, a harridan ex-secretary) who has been forced into system administration.
3. The MANIAC. Usually an aging cracker who discovered that neither the Mossad nor Cuba are willing to pay a living wage for computer espionage. Fell into system administration; occasionally approaches major competitors with indesp schemes.
4. The IDIOT. Usually a cretin, morpohodite, or old COBOL programmer selected to be the system administrator by a committee of cretins, morphodites, and old COBOL programmers.

How To Identify Your System Administrator (a field guide)

SITUATION: Low disk space

TECHNICAL THUG: Writes a suite of scripts to monitor disk usage, maintain a database of historic disk usage, predict future disk usage via least squares regression analysis, identify users who are more than a standard deviation over the mean, and send mail to the offending parties. Places script in cron. Disk usage does not change, since disk-hogs, by nature, either ignore script-generated mail, or file it away in triplicate.

ADMINISTRATIVE FASCIST: Puts disk usage policy in motd. Uses disk quotas. Allows no exceptions, thus crippling development work. Locks accounts that go over quota.

MANIAC:

        # cd /home
        # rm -rf `du -s * | sort -rn | head -1 | awk '{print $2}'`;

IDIOT:

        # cd /home
        # cat `du -s * | sort -rn | head -1 | awk '{ printf "%s/*\n", 
+$2}'` | compress
